Before I upgraded my system, I used 2GB of ram with ZFS on root, no UFS 
on the system.  Right now my ARC is 17GB, and in some situations it 
seems slower with the excess caching.  Here are the memory settings I used.

vm.kmem_size="512M"
vm.kmem_size_max="1024M"
vfs.zfs.arc_max="512M"

One major difference is I'm using amd64, not i386.  Although ZFS works 
on i386, it uses a lot of 64 bit math, for performance reasons you 
should use ZFS on amd64.
