My MacBook Pro Core 2 Duo gets slower - why?

post #1 of 3
Thread Starter 
Hi!
I bought a MacBook Pro 15" Core 2 Duo 2.4 Ghz in February 2009. It has served me fine, but in the recent months it has become increasingly slower. I see the rolling ball quiet often, which I didn't do two or just one year ago. Also sometimes the computer just slows down or get stuck in some operation without the rolling ball.
Have you any idea what is happening?
I am a power user. I use the computer every day of the year, mainly for work, but also in my spare time. I use iWork, Safari, Microsoft Office and Adobe Lightroom 3 for picture post processing. I guess Lightroom is the most demanding of those programmes.
I have done some maintenance, for example with OnyX. I also repair permissions regularly.
Have you any hints of what might be wrong?

And it, obviously, slowed down my MBP.

I suppose that Lightroom is rather heavy, when processing pictures. But the slow down occurs not only when Lightroom is used, but also when just using iWork, Safari and Mail.
Actually I think I have experienced similar things with former Mac-computers. Can there be some kind of cluttering of the whole system?

I have not been replacing the hard disk and I have no suspicion about the HD having problems. But I do notice, that when I use Safari heavily, it does take many resources from the RAM and CPU.
