No, I'm not sure. Indeed, I'm quite positive that the applications
have bloated themselves up enormously. Take Firefox, for example. I
have mentioned on here before how I think it's the biggest pile of
crap to hit the desktop in a very, very long time. I loathe it with a
passion. But it seems to be the best of a bad lot right now (Opera
aside, but I'm ignoring them for ideological reasons -- despite being
a very good product, I really do like to run a 100% free software
system[1]). But are applications the whole cause? I'm not so sure. As
I said, latencytop seems to show an awful lot of waiting for CPU going
on. And even if it's not the cause of my problems right now, I'd still
be interested in learning how to tune the scheduler anyway...

The same things I mentioned. Working on multiple images in GIMP,
changing between tabs in Firefox etc.
