IMNSHO the bottom line is this - if you want to have a fair
crack at seeing what ZFS can do for you, you need a 64bit
processor and 1Gb of ram.
let's be more honest and say 4GB of RAM and dual 64-bit procs
No, that's not necessary.
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 :
bash-3.1# vmstat 5
kthr memory page disk faults cpu

I would have thought you'd realise that showing a mere 15 seconds
worth of vmstat output -- with a 5 second granularity -- is pretty
useless to illustrate your point.

Again, the above does not show data with enough granularity
to prove your point.
