Have you tried restarting? That usually speeds things up a bit, also try a disk repair and permissions repair in Disk Utility, as that might also help.
 
How full is the hard drive .. you always try to keep 6 to 8 GBs of hard drive space free to keep the Mac from running slow is one way that i can think of right now .. :eek:

That reminds me, make sure you don't have too many items on your desktop, otherwise it will cause it to be very slow.

This is a good one to check and might not be obvious--my mom has that exact computer, and she has a tendency to save EVERYTHING on the desktop.

I was trying to figure out why it was running so slow at one point, when I realized there were upwards of 1200 files on the desktop. This does not make the computer happy for whatever reason.

If that ain't it, restarting, run a repair permissions (via Disk Utility) for the heck of it, and make sure you have a few gigs of HD left over, as already suggested.

If none of those help... maybe you're running some background process or something?
 
Also, some of add-ons like services from 3rd party apps could slow down main applications. Try create a new user account or clean out something.
 
Suggestions...

1) Repair permissions.

2) Check your Spotlight status (if running Tiger). Is it re-indexing?

3) Use OnyX to clean-out all your caches, log files, etc.

4) Keep at least 5GB free on your drive at all times.

5) Check Activity Monitor to see what's eating all your CPU cycles.

I'm runnning a 1GHz iBook G4 and it's still as fast as when it was new!
