Apple Logic Pro /LogicExpress Discussion

I just switched from Logic 6 on OS9 to Logic 7 on OSX (Tiger).  At this point, I don't know my way around all that well.  In OS9 there was a way to allocate RAM to Logic.  Is there a similar way to do this in OSX?  Is there a need to?  I am running a G4 PowerMac and things are a bit slow.

Is there anything I should (need to) do to speed things up?  I already 
altered some things in the Directory Access.

Thanks,
Dave
