SuSE 9.1 Diagnostics Apps?

I'm suddenly having a weird issue with my SuSE 9.1 box. It is a 1.9GHz AMG processor, but it's acting like it's a 200MHz processor or something. Takes like 10 minutes to boot up and pulling up a webpage via localhost transfers at 30 bytes a second! I'm assuming this is probably a processor issue (it does the same thing booting into XP Home), but I need to track down exactly what's going on. Can anyone suggest a diagnostics program that will show me stats on things like how fast the processor is actually running? I've looked in YAST but don't really see anything that will do it. Thanks!
