SWAP1 - 1GB SWAP2 - 1GB
Apparently the kernel can balance loads between 2 swap partitions like it can with multiple processors, so it would make sense to have 2 1GB partitions rather than a 1 2GB partition. However this machine rarely swaps.
Having both swap partitions on the same drive and drive controller won't buy you much, but having two of them on completely separate drives and controllers (say a multi-controller SCSI system, rare, but hey maybe you have such a beast) allows for somewhat better performance as long as the kernel chooses accurately which disk is "quieter" when it goes looking for swap space.
I've never looked at the swap code nor tested this, but it stands to reason that two swaps on the same drive and controller shouldn't buy you much of anything in the way of performance.
