Well... i didn't use opensuse 11.0 on my main laptop, so i can't tell for sure.
Also, my workstation is much faster than the laptop, and so the effect is only
noticeable when you know what you're looking for. (ok, i admit that i was
exaggerating - on the notebook it's "much slower", while on my workstation it's
"slightly slower")
A colleague complained that ff3 (which we have since 11.0 iirc) has problems
with scrolling, and that brought me to play with it somewhat, because i know
that scrolling in ubuntu isn't that bad even on older hardware.
some findings:
- it only appears when you have "smooth scrolling" turned on. (-> lowering
severity)
- the slowdown appears to be quite dependent on CPU speed (i can't tell for
sure, because i have tested only on three machines so far, all Core2 Duo, one
is 1.5GHz, one is 1.8 or something and one is 2GHz, and the problem was rather
visible on the 1.5GHz machine, but quite negligible on the two faster machines)
- still, with smooth scrolling, on the 1.5GHz machine, the ubuntu version
appears to be comparable to the 32bit official version on suse, and noticeably
faster than the 64bit suse version.
it is possible that there is some kind of power saving in suse that's keeping
the clock speed down. i will check that. but still, the difference between
32bit and 64bit is slightly disturbing.
also, i'll do some testing on clean profiles, my main profile (shared between
the three versions) has quite a bunch of extensions
