System:

Current CentOS 4.2 Gnome GUI

The system runs 'idle' at around 70Mb memory used and 4% cpu usage.

But whenever I go to start a task:

Start Gedit, Services tool, a Terminal window, Firefox

It takes a minute or so. CPU mayyyypeak at 100% briefly then come down. Memory has yet to exceed 100Mb usage.

Any pointers of where to look to see why it is slow?

Why it is slow is easy ... RHEL-4 (and therefore CentOS) doesn't work correctly in GUI mode with less than 256MB RAM.

If you run top and look, you will have lots of SWAP usage ... which is simulating system memory onto hard drive. This is VERY slow and makes things take forever :)
