The only big performance issues are swap partition vs. swap file: the
swap partition is a lot faster.

Other than that, it's how much swap that you actually use that impacts 
performance, not how much is available.

If you have more than one drive, it is smart to make two smaller swap
partitions, one on each drive, rather than one large partition.  This
way, the kernel can "stripe" the data between the two (it does this
automatically) to maximize swap performance.
