Best practices say you should have some swap, but if you're using a lot of swap, it's highly likely that you have under-provisioned RAM on your system. I tend to never devote more than 2GB of swap to a system, regardless of the amount of physical RAM available.

The downside to this in the Windows world (yeah the question is linux based) is that a full memory dump isn't possible if you do this. – TheCleaner Jun 6 '13 at 21:52
@TheCleaner The same is (generally) true in the Unix world as well -- crash dumps are written to swap if the system panics. Of course if you're having kernel panics you've probably got bigger problems than how big your swap partition is... – voretaq7 Jun 7 '13 at 2:30
