Since Mojave beta, I've seen network slowdown on the one Mac here that can use it [which means I can't run any proper comparison]. I'm getting approx 11MB/s [90mbps] ish on internal or external transfers. Speedtest agrees with this 90mbps, on a line rated at 200 & which I can repeatedly achieve on any of the other machines here - consecutive tests on 2 machines i.stack.imgur.com/KSeHL.png

This makes me think it's "this machine" in some way, shape or form.. but I can't figure out how to start to analyse it. I'd make it a question, but it just seems a bit vague. Any clues where to start? or even 'how to turn it into a proper question'?

This is all on gigabit Ethernet, btw, so I ought to be able to get something closer to 100MB/s on an internal transfer [give or take drive speeds]

meh... change ethernet port, get full speed :/ I'd already cleaned everything, no clue why that would be so.

This question has just been viewed 1,000 times now, which means that the questino is germane, but with so little voting activity I think readers find the whole thing unsatisfying. There's only one answer, from an unregistered user named "Anonymous Person".

Has anyone else had this problem and would have something further to share? The current answer is unsourced, I have no idea if it's right or wrong so I won't be accepting it in its current state.

Best guesses...1) Very few people are still running 10.8 so have no comparison. 2) could possibly be a slow pinup on the drive, causing it to hunt for a net boot solution before the drive spins up [total guesswork]

in the US many estimates put iOS higher percentage wise then Android

this is shocking to me gs.statcounter.com/os-market-share/mobile/…

other countries matter for sure but we definitely have some spending power/influence

worldwide android is much more popular though
