@allquixotic a good question for you!

Q: ext4 vs btrfs performance on SSD array

Nikolai GrigorievI am observing something that I cannot explain. I am trying to come up with a good filesystem configuration using HP P420i controller and SSDs. Out of curiosity I have tried BTRFS (still unstable so I can't really expect to be able to use it) and noticed that the read speed is about 150% of ext4 ...

 
12:23 AM
@allquixotic: The room ;p
also I try to write for the blog when I can
 
1:12 AM
ooh. Apparently you can connect banana clips to each other.
0_0
I'm watching the tested arcade cabinet video.
They... actually have what looks like a MIB CRT
 
Bob
1:37 AM
@jou banana plugs*
 
;p
Yeah, those
 
Bob
alligator clips, banana plugs
 
Bob
2:14 AM
@allquixotic Do you happen to know if xrdp can do NLA?
and it looks like, at least as of 2012, fail2ban won't work with xrdp because xrdp doesn't log the remote host on auth fail
 
2:32 AM
Yay
my dad got fed up with me having trouble 'acquiring' a copy of matlab, and got me to buy him a copy ;p
 
Bob
o.O
I don't review much... the comment made sense, but then the actual edit confused the fuck out of me
 
Eh. Turns out my backup worked ;)
If I screw something up, I can 'just' reimage from my most recent image and get things working again
excellent!
 
@Bob wtf?
 
Bob
2:48 AM
@MichaelFrank review audits -_-
 
2:59 AM
Yea, just wtfing at that edit
 
 
7 hours later…
10:21 AM
man, its quiet today
 
Bob
achoo
 
10:37 AM
eh, rtorrent install went perfectly in ubuntu
I'll throw a vm together and try to work out why it won't work in fedora at some point
 
@JourneymanGeek Because Fedora!
 
@MichaelFrank: partially cause things are different, and I was messing with too many variables at once ;p
 
apparently fedora packages xml-rpc enabled rtorrent, but the layout they use for lighttpd modules are different
 
11:40 AM
Why does this keep happening? :(
In case it's not apparent, the mouse-over effect of clicked context-menu items permanently remains on my screen
Reproducable and only resolvable by restarting uxsms
 
Gives up, downloads unix tools for windows and goesd to get coffee.
Over two hours in powershell and I still have not got it to do the same as a simple cut -f -d"(" does in unix
 
11:57 AM
@Hennes Try echo cut: invalid byte or field list
That seems to be the equivalent for me ;D
 
12:15 PM

I am only interested in part of those output lines

12:27 PM
@Hennes I tend to install GOW for that
 
I was looking for something which could run on a regular win7 installation at work without needing to install extra software
 
OH MY GOD IT IS SO FAST!!!
30sec to download Ubuntu O_o
 
Hey guys
Does anyone here know anything about Centos 6 and php-mysql client?
 
12:53 PM
@MarcRasmussen: not really, but I suspect its the mixed repos that's the problem
@ThatBrazilianGuy: whoa. Did you finally get moved off the internet backroads?
 
@ThatBrazilianGuy Jelly.
 
@Hennes: Thats true, but I think you can extract and run gow too
 
@JourneymanGeek Yesterday I found out the forensic lessons I'm having are taking place on a building that's the backbone for all the city's government institutions
 
ah hah!
 
...I think I won't be passing the lessons. For the next few years. :P
 
12:56 PM
@ThatBrazilianGuy: rofl
 
 
1 hour later…
2:02 PM
Oh neat
I'm reasonably certain I managed to kill one of my cheapo USB drives
hm, that's not cool
I seem to be having issues accessing my ttrss instance
 
@ThatBrazilianGuy Neat!
 
and irc bouncer dropped out
 
Hey guys
Moving a folder from local linux machine through ssh how come this doesnt work?
scp /var/www/system_learningbank/ root@89.104.220.207:/var/www/system_learningbank/
root@89.104.220.207's password:
bash: scp: command not found
lost connection
 
Oh nice. the VPS I run a bouncer and tt-rss is down ;p
 
Bob
@Hennes what on earth does -f do without an argument? (what @OliverSalzburg said)
 
2:16 PM
actually no, the host's website is down too
 
Bob
@JourneymanGeek is it that one hosted by your friend? :P
@MarcRasmussen try installing scp
 
@bob on the server? its a CentOs server
 
Bob
@Hennes Also, the equivalent of cut in PS/.NET is usually String.Split
 
@Bob: kinda
 
Bob
@JourneymanGeek ...how can that be kinda
 
2:22 PM
They got bought over, so I have no idea how long I get to use the VPS
 
Bob
O_O
so... you managed to carry over a free VPS to a company you don't know at all?
awesome :P
 
@Bob: I DID mention I needed to move out, right?
 
Bob
@JourneymanGeek guy wants to build this computer for gaming :P
> Current games I play are:

GTA
CS GO
TF2

One of the main games id like to play is Watch Dogs I know I know its had its up and downs but id like to give it a go with the Worse Mod ofcourse.

Not sure if my proposed replacement is over kill to get the best experiance.
> overkill
You think?
 
not reallly?
tho
will that card fit in that case?
 
Bob
@JourneymanGeek barely
287mm < 290mm
lol
@JourneymanGeek come on, devil's canyon i7 with liquid cooling?
 
2:35 PM
@Bob: that's remarkably close to what I MIGHT have built ;p
given a slightly less limited budget
 
Bob
@JourneymanGeek still completely overkill for gaming
unless you were doing something with simulation or a shitton of physics on the CPU
might as well get an i5
 
@Bob: I'd argue there is no such thing
;p
 
Bob
@JourneymanGeek consider you'd have 3/4 cores sitting completely unused most of the time
 
@Bob: >_>
annnd?
 
Bob
you're paying extra for no benefit?
 
2:40 PM
if it wasn't a K model, the water cooling might be utterly silly. Its a ricebox ;p
 
erm. You do realise I'm currently chatting on a quad core, core i7 with 16 gb of ram, right? ;p
 
Bob
the i7 mostly adds HT
single-thread performance is the same
 
@Bob You'd be surprised how frequently a 4.4GHz i7 gets maxxed out when not doing stuff like video encoding.
 
Bob
@JourneymanGeek I'm talking about recommending hardware for a guy who says, and I quote, " I mainly use it to play games.".
I have an i7. And even then it's mostly sitting wasted...
 
2:42 PM
@Bob: I nearly went with 32 gb of ram and water cooling on this rig
I'm kinda glad I didn't but...
I could do 90% of what I do on that little celeron box I bought last week
 
Bob
@DarthAndroid Do tell.
 
(of course, this isn't a gaming rig)
Other than the video card, its built so I could run VMs.
 
(Granted, I abuse that computer like nobody's business, but... eh.)
 
Bob
@JourneymanGeek that was the main purpose of mine
even then I find it difficult to max it out
 
and I could probably upgrade the video card for some benefit
 
Bob
2:44 PM
hence not bothering to upgrade for the last four years
 
but its a Gforce 660, Its good enough
oh. and that.
I got sick and tired of getting kicked off the shared box
 
Bob
we've long passed the point where modern midrange CPUs are powerful enough for just about everything you throw at them in daily use
 
@Bob: eh. If I was building a pure VM box now, I'd go with a core i5 with VT-D
Actually I went with a core i7 because I was under budget and I figured having vt-d would mean I could just stick more ram, and use it just to run VMs when I next upgraded
 
@Bob Dropbox, Crashplan, Outlook, console windows, task manager, skype, Chrome with a bazillion tabs, and whatever other background processes I have easily prevent the CPU from dropping below 10% utilization
 
@DarthAndroid exactly -- my issue isn't so much that a single task can peg the CPU (though during loading of many programs the CPU can be pegged for several seconds, so load times can still be reduced by higher single-thread perf) but that you have to shut down a lot of background stuff when you're on a low-end system to keep it sane
 
2:48 PM
There's never just one offender, but when you get enough stuff running, the CPU is always busy with something
 
Home!
 
Bob
@DarthAndroid 1. That's very different from maxing it out, 2. If those listed processes are causing significant constant utilisation, something else is wrong.
 
Bob
Also, don't talk to me about "a bazillion tabs" :P
 
@Bob Oh, not one of them is causing significant or constant utilization.
 
2:49 PM
I had it mentioned on the comms room, and I'm not sure if its a stupid question
 
@Bob a bazillion Chrome tabs are a lot more resource-intensive than a bazillion FF tabs
 
@Bob Oh, I mean that as a reference, since I know you understand :)
 
but what's the practical advantage of more processor cache?
 
Bob
@allquixotic Well, that's his fault for using Chrome, then!
 
@JourneymanGeek Less harddrive accesses
 
2:49 PM
on a processor?
 
Bob
I can easily go 800+ FF tabs with maybe 1% CPU utilisation
 
let me correct that
 
Ah, oh.
 
@JourneymanGeek (assuming you mean CPU cache) basically, instead of memory throughput being a potential bottleneck, that bottleneck is replaced with CPU cache bottleneck, which is a much, much higher ceiling
 
Bob
@JourneymanGeek That's very task-dependent.
 
2:50 PM
^
 
memory bandwidth and/or latency is pretty damn fast on, say, DDR3-2000 or so, and it'll be amazing with DDR4 coming out in the next few years, but cache on the CPU package is still amazingly faster than RAM
and having lots of data that you're working with frequently within the CPU cache prevents those requests from ever hitting your system memory
 
(this came up when we were talking about dinky little celery nucs, and how there mere meg of cache didn't slow stuff much)
 
Bob
If you're switching a lot between different programs in general use, it's not gonna make much difference. If you're doing some high-performance computing task, it'll matter more.
 
CPU cache is awesome for stuff like, having multi-hundred-megabyte data structures (trees, hash tables, arrays, etc) in RAM and having a program run through them processing items repeatedly in a loop with an O(n) or worse algorithm
 
Bob
2:52 PM
A tight loop doing some processing with all the data within the cache can be orders of magnitude faster than one that has to access system memory.
 
Aye.
 
a lot of programs we use on a daily basis have algorithms like those within them, but we often end up only processing smallish amounts of data, not many thousands or millions of items
 
I once got 15 times faster result when I added some coast.
 
Bob
Switching between FF and MS Word? CPU cache isn't gonna help there.
 
(Dos program using 400KB, the coast stick expanded RAM from 256KiB to 512KiB)
P1-era
 
2:53 PM
switching between FF and MS Word, RAM will help you
or at least an SSD as the page file, as I've demonstrated :P
 
@allquixotic: I'm a firm believer in as much ram as possible
 
Bob
@allquixotic I wonder what the speed difference is.
I can never remember RAM throughput numbers -_-
 
@Bob well, what's the throughput of DDR3-1333?
 
@Bob: Depends
 
Bob
@allquixotic ^
 
2:54 PM
Hmm, not as much as possible. But much more than is average
 
@Bob To give a better idea of what I mean by constant utilization, at any given time there are 20+ processes using on average 0.5% CPU. These 20+ processes are different every second, but there are at least 20 of them each second
 
Apparently if you have an AMD APU it matters a lot
otherwise, not much difference
 
my Samsung 850 Pro 128 GB is hard-capped at 3 Gbit/s by the original "eSATA-II" controller, plus latency for it having to go over PCIe -> QPI
 
Bob
@DarthAndroid I still think you have something weird going on. I haven't seen my process count drop below 150 in years, and it's often above 200. None of them are that hungry.
 
the 'GPU' on the APU shared the ram bandwidth. Faster ram help a lot in that case
 
2:55 PM
@Hennes I thought Intel iGPUs use the CPU cache too?
 
No idea if it holds for intels. I guess it should.
 
@Bob Crashplan uses a fair bit of CPU; I use it so I know :P even when you have nothing going on it is periodically scanning for any changes to files it needs to back up
 
@Bob I see it on both desktop and work laptop, never seemed odd to me. The processor is speed-stepping, so it's often at reduced speeds, but there's still always something going on.
 
Back when APU were new you extra fast (and extra expensive) RAM was worth it
 
Bob
@allquixotic Not Iris Pro, the one with the extra eDRAM cache
 
2:56 PM
@allquixotic Crashplan doesn't scan, windows notifies it
 
@Bob it should be able to use the eDRAM and the L3 and the System RAM, IIRC
 
Bob
huh, that eDRAM is also available to the CPU O_O
 
@Bob Yep :D
 
It only has to do a scan on startup
 
@DarthAndroid I figured it wasn't polling, but the kernel has to callback whenever the VFS layer mutates a file descriptor or metadata, I guess
 
Bob
2:57 PM
@DarthAndroid Mine varies between 0 and 7-8 (usually 0 or 1 while you watch it). If it was hovering above 10, I'd consider something wrong.
I wonder if Intel can sue over that.
 
@Bob DDR3-1333 peaks at 10.666 Gbit/s.
 
Bob
also, eww
$200 for that pile of junk?
 
That's way faster than what an SSD would be capable of, even with eSATA version 3
I've occasionally applied enough memory pressure on this system (the one I'm typing on now with 2 GB of DDR3-1333 and the page file entirely on the Samsung 850 Pro attached to eSATA 3 Gbit/s) to cause severe swapping... and when I try to restore, say, an Eclipse-based application, I see black widgets (the textures have been swapped out to disk) for about 1/2 of a second.
When the pagefile is on the HDD, I don't even see the window itself for 3 or 4 seconds, and then the textures take about 9 seconds to fully load.
Eh. It's an improvement.
12 seconds down to 0.5? 8 GB of RAM still runs circles around it, but the SSD in turn runs circles around the HDD.

Q: Why does everyone face the same way on the transporter?

congusbongusWhen the away team prepares to beam down, they invariably assume the transporter formation: standing upright, usually with arms slack aside, all facing the camera. When they beam down, they reappear in the same formation and poses, as that's how the transporter works. However, they do this even ...

@allquixotic You should see my laptop.
Slowest modern HDD ever.
 
lol
is it one of those 4200 RPM or so? I've seen those going in small laptops lately for power savings
less RPM translates to less power consumption, and it's still very economical to cram, say a terabyte into a tiny hard disk
 
Bob
3:04 PM
@allquixotic 5400
but I often see queue times of over two seconds
actually, it has a UHS-I card reader, and I recently got some nice Samsung USH-I MicroSDs... could use those for swap, or readyboost
but it'd probably burn out the NAND pretty fast
 
geez, 7200rpm disks are slow enough... unfortunately, they do drain a significant amount of power, and it's hard to design an HDD that can reliably and quickly do many start->stop cycles, so you have to keep it spinning constantly, which drains energy :/
my next laptop will definitely have an SSD, I can say that for certain... you just have to deal with the expense and/or write cycles and/or capacity... there are way too many downsides to HDDs in laptops. shock damage, constant power drain, slooooooow, etc
you can make HDDs work on a desktop with the right RAID controller ;) and energy is less important
 
Bob
@allquixotic I'm pretty decided on that now, too. Unless it's another emergency laptop purchase -_-
I have a nice 2TB portable HDD for anything big
namely, videos and ISOs
 
you might want to buy your next laptop with the cheapest-available storage solution (just because they require you to have one -_-) then buy a Samsung 850 Pro to stick in there
 
@allquixotic: I think some of the early 4tb drives are 5900rpm
 
3:08 PM
best tradeoff between durability, capacity and speed that I've ever seen in an SSD
 
@allquixotic: or whatever's replacing it at the time
 
Bob
@allquixotic I don't really like fiddling with laptop drives :\
 
*and price, too, let's not forget that
@JourneymanGeek true
 
Bob
actually
saw some decent SSD prices recently
 
still, when you look at the SSD market overall, you see a lot of offerings that are seriously skewed in one direction or another
 
Bob
3:09 PM
I might actually consider that, but...
 
Samsung does make generally well rounded drives
 
the enterprise shit is skewed on the price axis to beyond affordability
 
Bob
580 GB used... I wonder what for O_O
 
the cheapo shit wears out too fast (hello OCZ)
 
I have a 840 (not pro) and its awesome
 
Bob
3:09 PM
and let's not forget the damn 25 GB recovery partition
 
also some of the cheapo SSDs are actually slow
hard to fathom, but yes
 
but I'll likely consider getting a nicer, non TLC ssd in future, imaging it, and sticking it in my laptop
@allquixotic: even compared to spinning rust?
 
Bob
hm
@allquixotic do you know how to migrate an UEFI OS?
 
(Granted, I usb booted... and that was horridly slow. Until the drive died ;p)
 
@JourneymanGeek well, some "SSDs" being sold at alibaba, amazon, etc are little more than one or two microSD cards. you do the math. :P
 
Bob
3:10 PM
is it enough to just clone the partition(s)?
 
@allquixotic: I've seen kits for those ;p
 
@Bob grabbing the entire disk at a block level will do it... other than that, you'd have to grab every partition, since the EFI SYSTEM PARTITION is just a regular partition, there's nothing in the "MBR" (the GPT equivalent) except a list of what partitions there are and what are bootable
 
(and mini PCi, 2 slot sata cards. ... which mystify me)
 
there's no actual boot code in the GPT outside of what's within the partitions themselves, so if you can't for some reason clone the entire disk at a block level, taking all the partitions should be fine
 
"Oh, I don't have enough drives. I know, I'll remove my wifi card and put 2 more hard drives there"
 
3:12 PM
just make sure to set the correct flags on the partitions (mirroring what you have now) when you restore them! :P
you'll see the flags in gparted or similar
 
Bob
@allquixotic I can't clone a 750 GB HDD onto a 240 GB SSD, unfortunately
that would have been the obvious solution
 
@Bob: in theory you can resize and do it?
 
Bob
eww.
 
well like I said the GPT only keeps track of flags and the list of partitions and their start and end locations in logical blockspace (and their optional "label")
copying the partitions as they are, plus their flags and labels, should be fine
good thing you aren't booting Linux by GUID though because copying over your partition would probably change its GUID
for Windows, worst case, you just have to use bcdedit to re-do the boot code in the EFI SYSTEM PARTITION
which can be done from the recovery console on an install DVD
 
Bob
now if only I had such a DVD :P
 
3:15 PM
@allquixotic peers at the shiny new RAID card next to the desktop. (SAS2008 based)
 
@Hennes what make/model? I have an Adaptec 6405E
 
SuperMirco SMC2308IT, revision 16.00.01 IT with chipRev 05
Just writing all that data down :)
 
huh. not familiar with
 
Bob
oh yea, there was that msata slot... I really need to see about putting an ssd cache in there
 
careful with mSATA SSDs. I have one in my NUC that's about as slow as a HDD
 
3:17 PM
Small low height supermicro card. PCE v3 x8, SAS2.0, two port and two breakout cables to SATA
 
Bob
@allquixotic brand?
 
it's probably two microSD chips in some kind of striping
 
The breakout cables are annoyingly stiff.
 
Bob
I'm more worried that it won't work at all
 
@Bob myDigitalLife or something?
 
3:17 PM
Unlike the two already in the desktop
 
Bob
damn HP whitelists
@allquixotic ...that's a forum
 
o
let me search my email :P
 
Bob
anyawy, I was looking at a Samsung 840 Evo
Read Speed (MB/s) 	540
Write Speed (MB/s) 	520
Random Read IOPS 	97,000
Random Write IOPS 	66,000
Maximum IOPS 	98,000
I'd actually trust Samsung's specs
 
Bob
...that's your own fault for buying that shit :P
 
3:18 PM
-____-
 
don't blame me! :(
 
@allquixotic: Who can we blame? ;p
 
@JourneymanGeek the entire world? is easier to keep count, no?

turn off your laptop nao or it might catch fire!
 
Bob
> Based on the nature of this issue, HP is requesting that you immediately discontinue use of the subject AC power cords by removing it from the wall outlet and ordering a replacement AC Power Cord upon verification from the program Web site.
NOTE:The notebook will function using battery power.
Yes, because my laptop will run long enough for the delivery...
... ... ...
 
> The notebook will function using battery power.
NO WORRIES! WE GOT U COVERED BRAH
 
Bob
where do they think these batteries get their power from?
 
just buy 5000 batteries to last through the wait
 
Bob
it's like... "don't worry about unplugging it, it'll keep running!"
well... thanks... that's kinda why I bought it
 
3:23 PM
do they make you ship the one you have back, then wait, then get the new one? or can they ship you the new one now?
 
Bob
@allquixotic not sure, checking now
I have a spare charger or two, so I can just do it one at a time :P
their problem if they have to pay twice, if they make me ship it
 
oh good, you have spares... that means you can risk your life in order to keep using your laptop, while you wait for them to ship you a safe one :P
 
once you get at least one safe one though you'll be fine
 
if its just the cords it standard
snarf one off a non HP laptop?
 
3:25 PM
is it the PSU inline with the cord, or just the cord?
 
Bob
just the cord
 
what, did they source from a shoddy manufacturer that uses wood as an insulator?
 
Bob

phew
 
as for that pc parts picker link you provided earlier, Bob, I think that guy isn't exactly going overboard, if he plans to play AAA games going forward. the 4790K isn't even the highest-end CPU available; he isn't going for the enthusiast platform! so you can give him credit for having restraint in that matter :P
 
Bob
now to test the replacement
 
3:27 PM
he's just getting the fastest available mainstream (air quotes) CPU available ;p
 
Bob
@allquixotic it's still more than necessary :P
 
good future-proofing ;p
 
Bob
the highest i5 is 30% cheaper
a good $100
 
Bob
future-proofing? sure, but if it's entirely unnecessary...
 
3:28 PM
meh, what if he has nothing else to spend that $100 on?
 
Welcome to SU Zoo
 
Bob
@allquixotic hey, he posted on a site that hunts for bargains and deals
 
@Bob I retract my statement
it's still more than necessary
you don't go trying to get a "bargain" and buy the highest-end CPU available
that's not how bargains work
 
;p
@Braiam: two dogs and a fox do not a zoo make. Unless its a chinese zoo, then the fox is also a dog.
 
Bob
ok, second charger also unaffected
...shit my brother has one too
need to check that tomorrow -_-
 
3:31 PM
hey, I'm a smilis sadis! I count in the zoo too!
 
@JourneymanGeek that would make it a pound
 
smilii sadii are native to the dreary, socially-repressive mid-Atlantic region of the United States
 
@JourneymanGeek two dogs, a fox, a raccoon, dinosaur...
 
Bob
> The system is not designed to do what you are asking it to do. If a SATA hard drive is installed the system will not look past that drive in the boot order. So when you have the mSSD and the SATA drive in there it is trying to boot only from the SATA drive, which is not bootable. The only way to have the mSATA drive be the Windows boot drive is to install a "bootloader" on the SATA drive, which starts the boot process and then hands off to the mSATA drive to complete the sequence.
O_O
 
in the section of wikipedia on smilis sadis about reproduction, it says "None." and moves on to the next topic about how they always complain of their low salary and limited buying power
the dinosaur doesn't belong in a zoo, btw
he belongs in a museum
 
3:34 PM
;p
 
Bob
This guy just needs to add a trust me to the end.
 
LOL
> I'm an HP employee, and I know everything about mSATA and "flatforms"! TRUST ME!
I work with HP employees, occasionally. Let me assure you, being an HP employee is no indicator of competency.
2
 
@allquixotic being something is not indicator of competency
 
I need to set up bt sync again
 
3:37 PM
@Braiam Wrong. There exists something that you can "be", such that being that something is a strong indicator of competency.
Being the first man to set foot on the moon is a fairly good indicator that you're a competent astronaut.
If you weren't, you probably wouldn't be, period setting foot on anything.
 
@allquixotic and as anything in life, there are exceptions
