Description BRULE Herman 2010-08-07 15:38:41 UTC

Version:           unspecified (using KDE 4.4.5) 
OS:                Linux

Hello, when I have heavy pressure on disk activities (4x copy of heavy file or folder), all kde is slow down, same writing in text editor like kwrite.
Thanks to minimize for the future version the disk access for the interface (menu, windows changing mainly with konsole with composing background, write in text editor, ...)
My wish it's have very reactive system like windows when disk is heavy used.

Reproducible: Always

Comment 2 BRULE Herman 2010-08-08 12:42:30 UTC

Yes it's possible. I do very frequenly copy, KDE under windows not slow down but under linux slow down.
And it's crazy of lag into text writing or input writing...

KDE is not usable in version 4.4.5 too with old hdd of 20GB.
And on my system (8GB memory, 2TB of hdd, quad core), the menu after long time have difficult for open it. (Keep all entry except icon into memory for improve the speed and update only via event like inotify or solid, for have any hdd access when try open the menu)

Is this still a problem in recent versions of Plasma 5, like 5.19 or later?

Note that we are working on a generic solution to this issue via systemd slices and cgroups, which will allow us to boost the CPP and IO priority of the frontmost app, preventing these kinds of frustrating hangs and freezes.
