So my NAS has been up and running for a little while now, doing a lot of transfers and some rsync's to my QNAP for backups. I have 16GB of RAM in it right now in a RaidZ1 config (3 drives), yes I know that might be a risk, hence backups to the QNAP. I noticed that I am pretty much sitting at 13GB wired all the time, 2GB free. I get transfer speeds normally around 110 MB/Sec, maybe a few MB/sec faster writes. But I know that at 110MB/sec, thats only 880 mbps, so only about 88% of Gigabit ethernet... I know everyone says more RAM is better with ZFS, but do I really need more RAM, its only about 150 bucks for another 16GB's, not cheap but not to expensive. Will that extra ram get me about the 95% network utilization? Maybe 120MB/sec reads and writes? Or should I just leave it as since the system say's it has 2 GB of RAM free so it isn't a RAM bottleneck?
