Actually, since the kernel is doing a context switch to access memory, 
everyone is getting the penalty, even if you have less than 900mb ram IIRC.

For your setup, unless you're running a huge oracle or db2 database, 
2g/2g might be a good option for you.

But, you might just want to stick with 4g/4g unless you have some 
performance problems.
