Lion memory and processor fix
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!
MacBook Pro, Mac OS X (10.7.2)
