2 "Mega" Bytes?  Surely that's a typo, but is it 200MB?  2GB?

Those that know ZFS will want to know the primary use / load of this system.

Subject: zfs tuning

I would welcome some advise on zfs tuning. Coming from solaris I need 
this info.
The system only has 2MB of ram. No problems running solaris11 in it so 
far so FreeBSD should do just fine too, but who can suggest some 
settings for:
vm.kmem_size
vm.kmem_size_max
vfs.zfs.arc_max
vfs.zfs.vdev.cache.size
Mind you, it's for a 2MB FreeBSD-8.2 system; no X; serving mail, web, dns
