Yep, but if you fall into the category of guys who need the
machine for other work than running ZFS benchmarks (remember,
we are USERS....), that's a configuration worth to consider....
Good values are estimated best by thingking about the typical
and worst case usage of the machine, there's no general guideline,
a little bit of experimentation will tell you over time what's
best for your systems.
