Theoretically, it should make for faster syncing and/or rebuilds also. I base this on the assumption that swap is enabled for syncing/rebuilding (I can't remember for which or is it both?).

The player software expects to be able to allocate upto 24MB of RAM. Normally this would come from 8-16MB of RAM (depending on empeg type) and 16MB swap.

So having the extra RAM should help there as well which can consume a fair amount of time. Not something you do every day but nice if it was faster at least.
