Applies to kernel 2.6.4-rc1-mm2.
Run X at about nice -10 or -15.
Please report interactivity problems with the default scheduler
before using this one etc etc.
So far i noticed:
with default scheduler:
When I run emerge sync (I am on gentoo) and finally the cache on disk
gets updated (very heavy disk activity), default scheduler (in
conjunction with cfq, haven' tried other) causes a schmall pause of 1-2
seconds when I use my browser, ie mouse cursor is ok, but I cannot
scroll for that time.
your scheduler: I tried it with the "love-sources", so maybe that patch
"steel300" incorporated was already a bit outdated, but I dunno. It had
the same version as above. When I click on a link in thunderbird and it
opens up in firefox (is started and just a new tab is created) the
mouses stutters for a brief moment. This didn't happen with default
scheduler. I dunno if above sympton happens with yours.
I haven't reniced X withy our patch. But I did it once and I didn't see
much of a difference. (I dunno if the mouse stutter went away then...)
bye,
Prakash
