I installed SL on a separate partition but didn't try to start using it regularly until last week. Lots of slowness, apps taking forever to launch, computer almost totally freezing up. I honestly thought my hard drive was dying. I went to the Apple forums last night and it seems to be a pretty common problem and Safari and old Quicktime plugins may be the culprit. I cleaned out all my of QT plugins and the divx plugins. Then I switched Safari to 32-bit mode. Things seem to be working fine for now.
