1. In your post you are using dedicated partition for swap. Did it provide
any advantages versus swap on ZFS volume?
2. You are suggesting to set 'vm_kmem_size' value to 150% of RAM. What
pros. and cons. against following formula:

vm_kmem_size = RAM / 2
vfs.zfs.arc_max = vm_kmem_size - 512M

3. Could you be more verbose about your ZFS layout, what major advantages
it provide against for example the following:

but I need more info.
