performance L2 cache

[astudentis]

what difference in performance can i expect between 3mb vs 6mb L2 cache?
what is the purpose of this cache?

I wont go into the details of how it all works but I own a new 2.4 3mb level 2 cache Macbook Pro and I am disappointed by its general responsiveness which I personally find intolerable. I then used the mid range Macbook Pro 2.5 6mb level 2 cache and it is clearly more responsive. Someone else may want to go into the technicalities of it all for the OP
