Public bug reported:
After a while of using Hardy, I've found that unlike Gutsy, heavy disk
usage by any one process (caused by things like launching Firefox or
Openoffice, or installing packages), causes other processes to be
starved of CPU time.
On a machine running Hardy, try:
cat /dev/urandom > ~/test
whilst playing some music, or even just moving the mouse around. The
mouse starts to jitter a bit, and the music starts to get choppy. (I've
noticed that choppy music occurs more with Rhythmbox than when using
totem or just a gstreamer pipeline, but it still happens whatever you
use.)
This kind of starvation doesn't happen if you just increase CPU usage
generally, by running something like
cat /dev/urandom > /dev/null
or just by moving windows around a lot.
This is definitely a regression on Gutsy for me. I'm finding that listening to
music is no longer pleasant if I'm trying to start programs or install packages
at the same time, for example.
Can anyone help?
