Specs:
I have a early 2011 high-end 15" MBP with Kingston 8gb ram 1600mhz. Rocking the original 750gb hd for now until I get my SSD. Did a clean install of OS X Lion.

What I did:
I installed Windows 7 Pro via BootCamp and it runs smooth, fast & reliable.

What my issue is:
When I am in Mac OS X Lion my system runs slower, like a lot slower since I installed Windows 7 through Boot Camp. As I said I have 8gb of ram and it always shows that only 4gb is being used / free the other 4gb is like in a VM reserve or something. I've checked "About This Mac" and both sticks are reading fine and everything shows that it's working but for some strange reason all of my Apps are slower. Handbrake used to take 15-20 minutes and now it takes 45- 1hour same with RipIt. PDF's take longer to load (1-2mb documents) along with excel and word files.

Any ideas? Need more info just ask.

When did the MBP start running slower? Did you do a clean install of Lion?

There are people reporting that after they installed Lion on top of Snow Leopard their machine got slower over time. Those same people did a clean install and Lion was as quick or quicker then Snow Leopard. Clean install is not a requirement. Sometimes it is the best way to resolve this type of issue. If you decide to do a clean install make sure you backup your user data first. I would also suggest re-installing any applications from scratch after the clean install.

EDIT: Doh! I just re-read your post and you clearly stated that you did a clean install. Sorry.

Try to reset your PRAM and/or run disk utility repair disk permissions.
