I am running AL 9 on a Macbook Air, and everything works fine. Except the when I'm running a set with too many samples, then my Ableton starts constantly buffering multiple samples at random times. The buffering slows down the program, sometimes to the point of having my playing samples stutter or sometimes to the point of freezing Ableton.

I'm using a External Hard-drive to store my songs, which I was once told would help with this problem, and it did to a small extent, but not completely. My set includes a little more than 100 songs, with some audio and midi effects.

How can I solve the buffering problem, or at the very least, optimize my Macbook for Ableton even further?
