I have 

tmpfs    /tmp   tmpfs  rw,size=4280000000

I would suggest you don't use tmpmfs="YES" in rc.conf unless you are
being very conservative with a production server. tmpfs is nominally
experimental, but it seems to be very stable, and it's much more memory
efficient than md devices.

It's not all that much faster due caching and soft-updates on hard
disks.

Do you have any particular concerns?
