32 vs 64 bit

(Correct me if this has changed, but I don't believe it has).
I prefer making my mogstored nodes 64-bit. Under a default 32-bit system
the pagecache is limited to under 800 megabytes, which limits how many
file objects you can have in cache. With a 64-bit storage node you can
bulk in the memory and get a lot more performance out of it.
It should be fine to mix 32-bit and 64-bit nodes. Nothing I've found so
far could cause issues with this.
