HELP! SSL Wave form lag and etc

My Scratch Live has been acting wacko wave forms lagging, repeatedly "loading crates", Delayed reactions from samples. Overall its just a pain while DJing and I have tried everything followed all the optimization, renaming my database V2, verify/repairing disk permissions, unchecking show I tunes library, deleting hella songs from my library, and etc etc. Im running a 13in Macbook pro OS X Yosemite (mid 2012), 8gb of ram, SL1 box, SSL 2.5, Two technics 1200s, DJ tech dif-1m.


ANYBODY have any other suggestions? Summer is around the corner and I'm trying to fix this disaster before peak season.
