I heard zfs is very ram hungry. Service looking to run: - nginx - postgres - php-fpm - python I have a machine with two quad core cpus but only 4 G Memory I'm looking to buy more ram now. What would be the recommend amount of memory for zfs across 6 drives on this setup? Also can 9.1 now boot to zfs from the installer? (no tricks for post install) Thanks Ben
