You won't be able to access that kind of stuff on the 'face' of OS X. You'll have to dig to it through terminal or using some kind of application that opens up more 'doors' than OS X does. Consider something like TinkerTool or Mac Pilot.How to make mac osx 10.5 run faster?
It's all automatic on a Mac. What is needed is allocated by the system. You won't make it run any faster by messing with it. It's not like the old system 9.
