I say zero swap, or if for some reason you NEED swap (for crashdumps maybe,
but I didn't think Linux supported that), no more than 2GB. With that much
RAM, you don't ever want to be in the state where the OS decides to page out
8GB of memory (for example) to swap. We have a few Oracle servers with
between 32 and 48 GB of memory and they all live just fine without swap.
