This has been a complete fix but it made a huge difference on my MacBook Pro's performance.

 

System:

2009 MacBook Pro

2.53 Core 2 Duo

8 GB Ram

50 GB free HDD space

Lion 10.7.2

 

As many have, I have had major issues with disappearing ram and processor overtasking. Apple has helped me get this undercontrol so I thought I would share the items we worked on.

 

First we deleted the Cashes in both Library folders. One was hidden so you need to unhide system folders to get to the one. This is there locations:

 

/Users/<YOU>/Library/Cashes

/Library/Caches

 

The next thing we did is reset the PRAM

I run Solidworks on this machine through VMWare Fusion running Windows 7 with good results although video performace is its weekness. I think this is totaly a video card issue.

 

Good Luck!

    Caches are not related to a videocard issue.  Someone reading your post might think they are.    That said, caches should only be emptied when they aren't browser related on a backed up system*:

    Sometimes if you inadvertantly empty system and User library caches while they are being written you can actually cause them to get corrupted.  Normally caches are there to speed your system.   Isolating a hardware from a software problem, you can certainly test if caches make a difference or not.

    One thing I noticed:  your free HDD space is not that high.  The consensus seems to be that issues may arise if you don't keep 15% free at the very minimum.  Sorry if you are already aware of this.
