It worked, but is perhaps not the best approach. Less than 4 or even 8GB ram is probably not recommended these days, especially since RAM is resonably cheap. Regards! -- Niclas P.S. The handbook should perhaps be slightly updated wrt ZFS, at least to clarify that tuning is only needed on i386 in the general case, and that you're usually better off running ZFS on an amd64 machine if you can choose. I'll look into it tomorrow...Received on Fri Sep 28 2012 - 21:23:00 UTC
