Application load time mainly depends on your hard drive, not your processor. That's why I said an SSD would probably make a huge difference in loading those objects (as it is way faster than a regular hard drive).
Besides, 8,8 Ghz? The world record is currently 8,3 Ghz and they had to use buckets of liquid nitrogen to make it sure it didn't instantly melt down.
I'm going to assume you have a 2,2 Ghz Quad core proc (which some macbooks use), but multiple cores cannot run the same program (when talking about the WE at least) to make it faster.
Only 1 core can, so that is a processing power of 2,2 Ghz.
