[Bug 555595] Re: Intel graphics performance regression in 2.6.32-19 lucid kernel update (was: Firefox Slows Down Compiz)

[Timo Jyrinki]

After a few days of using -16 kernel and 2.6.34 kernel and installing
all the lucid updates, I cannot currently reproduce the problem when
going back to -19. Putting the bug back to NEW. Previously it was quite
immediately seen as slower behavior in Firefox and Ubuntu Software
Center.

Meanwhile I have tweaked a couple of stuff like removed hal/hal-info
packages which are not needed anymore on lucid, and I'm not sure if
those, in addition to the updates, have anything to do with the problem
disappearing.

It's not to say that Intel wouldn't be relatively slow in lucid (and
before) - it's not blazingly fast and I'm not sure if there is some
specific part to blame or not. For example compiz cube rotation is
easily a bit jerky.

(another thing to note is that Ubuntu Software Center seems somewhat
sluggish even in this "normal" situation)
