Originally posted by TiborB View Post3) I must admit I'm not much familiar with cgroups and even what exactly your tool is doing. So I dont understand how your tool knows which application is "good" and which is "bad". For example, how it distinguishes opera from linuxdcpp or from some mp3 playing program... The active windows is not allways the right test, because mp3 player might not be in active window yet it needs some preference. Or do you have some list of applications split into some groups?
I documented the default scheduler. As you can see, it does not say: this process is bad, but tries to find groups that belong together and gives each group an amount of cpu shares. As opposed the normal: each process gets the same amount of cpu share.
The rules in rules/media.lua schould set a flag on your mp3 program, so it gets more cpu share because it fits the requirements of the media group.

Originally posted by TiborB View Post5) Is it possible to measure effect of ulatencyd? Probably not I think...
I personally find by desktop much more smoother when it's running.
Originally posted by TiborB View PostFor your information - perhaps you can mentioned it somewhere - I found that for Arch Linux two PKGBUILDS were created in AUR (arch linux users will understand what it means) - ulatencyd and ulatencyd-git (http://aur.archlinux.org/packages.php)
