Performance Issues

I'm having a bit of trouble with my laptop running Slackware. Whenever I am doing something realtivly intensive, the system just slows to a crawl. This includes when I am compiling a package, but even for simple things such as untarring a large package. I'm running a 3.0Ghz P4 processor with Hyperthreading - I really shouldn't be able to make this thing crawl so easily...

What could be causing this performance drain?

I did have to roll my own kernel with the cutting-edge mm patch in order to get my sound working - did I maybe not flip some switch in the kernel config that might be affecting my performance this much? I am leaning away from the 5400rpm drive being the major problem - even my mouse slows down in X when this occurs and the mouse cursor changing wouldn't be trying to access the hard drive. When I compile something, cc1 takes up about 25% of my cpu and most of my ram, but I never even touch my swap the whole time.

System info:
cat /usr/src/linux/.config
cat /proc/cpuinfo
hdparm -I /dev/hda
If anything else is needed just ask!

Ok - it took some work, but I figured out the problem. I looked in the kernel docs about SMP and it mentioned that you should have "Enhanced Real-Time Clock" enabled under device drivers -> character devices. I did so, recompiled, etc and suddenly everything started working as it should!

I should've known.....RTFM is the answer every time! )
