To be honest, I'm really not sure what causes it? Some larger maps I can understand, but there's two specific smaller maps that no matter what I do just lag really badly, and I have no clue why? I'm guessing it's most likely a script that I'm using but I'm not sure which one. Thanks for the advice, I'll have to have a look and see if there's anything these two maps have in common, that I've just missed.
