Make use of extra ram?
 

We'll probably be moving soon to a server which is got 3 times as much RAM as current one. Not that I need that much but it is just a coupon code that gives some extra features plus a discount.

Anyway I was wondering, what specific config options for mysql could be increased on account of having more RAM available to improve it's performance.

Any maybe the same question for apache.

Thanks in advance for any replies.
