let's be more honest and say 4GB of RAM and dual 64-bit procs
okay its not that bad, it does great with 2GB of ram on my box.
Perhaps I've found a sweet spot with b39.
I am beginning to think that ZFS is a feature of Vista because it
seems to eat all available RAM endlessly. My snv_52 machine here has a
zpool on it and a few ZFS filesystems. No one is logged in graphically,
there is one user, me. I'm doing nothing. Look here :

now that is without any zones running, but even with a couple zones
one being a large sgd, it still does well with only 2GB of ram, note
that all the zones are on zfs filesystems.
