How to speed up slow zpool scrub?

[krad]

That memory requirement really depends on your work load. I have run small
boxes with 2gb and zfs and they ran fine. They weren't doing filer or
desktop roles though I could get away with fairly easily. Having said that
I wouldn't build a machine now with less than 16gb unless it was very
special circumstances.
