Or raising the polling rate of USB mice above 10 Hz (as in ten - that’s not a typo).
I don’t know the answer, but I’m interested, what do you use that for?
Fortunately, copying or moving more than 1 GB to or from USB sticks without crashing the entire machine (no matter if NTFS or ExFAT) was solved last year, probably because of a kernel update.
I believe it has a lot to do with the default amount of dirty memory. dirty memory is mostly the write cache, which is unnecessary to have a lot of, as that does not improve anything after a certain point, but at best it can mislead you to believe that a copy opetation started with 200 MB/s and that it finished when it actually did not yet.
you can fix these limits with sysctl files. they are loaded on boot on typical systemd systems. suggestions are in the manjaro post, relevant for any desktop linux system.
maybe it’s worth to set these up even if you are good for now. It’s good to hear a kernel change could have fixed it though. maybe they have finally revised the defaults, they wanted to do that for a few years now…
