Initial NFS Test: Linux vs FreeBSD (769% slower)

As an appendum … I found this post http://osdir.com/ml/freebsd-fs/2012-10/msg00156.html that talked about mounting with the oldnfs  option, so tried that out … same speed …

I created two separate volumes, but both are on the same aggregate and the same size.
