Yea I only have 4GB of ram on my little HP MicroServer I use as a NAS with ZFS. The only issues I seem to have is that ZFS encryption seems to use more CPU than luks encryption, but it's still not too bad (the AMD Turion(tm) II Neo on it doesn't have AES instructions). I might upgrade it to something with a better processor because I do want to run de-duplication on my 14TB drive at some point.
