If I read them correctly, Artie and joemikeb are saying that you really are not slowed down, even if you are seeing in one place a percentage number that is high.

My question to you is are you experiencing a slow down? Noticeable lag time between mouse clicks and an event? Spinning colored beach balls? Slow opening of applications? Etc.
