Hello,
I notice since linux 4.8.4-1 that during high I/O operations ( hard disk, decompression of a huge zip/tar.gz file ) that my system seems to have "micro-freezes", I notice lags ( mouse doesn't response immediatly ) and some operations like a "pacman -Syu" takes much more time,
I have an old motherboard : gigabyte GA-P31-DS3L, socket 775, chipset intel P31, cpu intel dual core E6800 3.3 Ghz, 4 Gb ram,
I want to know if I am alone with this problem ?
smart infos of my hard disk ( western digital 640 Gb ) seems ok, no problems, so it's not a hardware problem, it's probably a bug in linux kernel
thanks

Possibly related to your I/O scheduler? I've found with the kernel's default I/O scheduler I would get hangs during heavy I/O operations on my platter-based systems.
See here: https://wiki.archlinux.org/index.php/Im … schedulers
I personally use the "Multi-Queue Block IO Queuing Mechanism" on all my systems (low/high end, HDD/SSD). It seems to balance the load nicely and minimise hangs/stutters.

thanks for your answer,
so it seems that the default setting for I/O scheduler in linux kernel package is not optimized,
but with previous versions of linux kernel I didn't have this problem, maybe it's a bug, a regression in 4.8.x kernel
