SuSE 10.1 Unusably Slow

I had SuSE 10.0 installed just fine, but I installed WinXP and in the process decided to install 10.1. Apparently a bad move, because though WinXP is running great and SuSE 10.0 ran better than any OS I've ever used, SuSE 10.1 is running unusably slow. I mean so slow that right after I boot, if I run konqueror, I can watch the bouncing konqueror icon suspend in mid-air multiple times. We're talking at least a full minute before it comes up. Forget about using it, that's 10x worse. Ideas? I have no idea where to start as ever since SuSE 8.1, I've not had any problems like this. -- Cheers, wmeler
