Hey, since i can't find any recent threads on the subject i'm posting here.
I've been experiencing for a while system lags (like ui irresponsive..) when copying 'big' files (~1Go) to any external drive.
First i suspected nautilus but using thunar, cp, vcp, etc... results in the same problems.
i'm using arch kernel (3.11.1-1-ARCH) on a ssd with noop schedulder, any hints ?

Have you tried any suggestion from the older threads, like https://bbs.archlinux.org/viewtopic.php … 8#p1033648 ?

yes, but no effects on the lags.

for me... this solves
From here:
https://wiki.archlinux.org/index.php/US … B_pendrive
If you experienced slow copy speed to pendrive (mainly in KDE), then append these three lines in a systemd tmpfile:
/etc/tmpfiles.d/local.conf
w /sys/kernel/mm/transparent_hugepage/enabled - - - - madvise
w /sys/kernel/mm/transparent_hugepage/defrag - - - - madvise
w /sys/kernel/mm/transparent_hugepage/khugepaged/defrag - - - - 0
