Subject: 2.6.5 NFS ready for production?

I'm trying to decide whether or not to even contemplate putting 2.6.5 on
our NAS server (single 2.4GHz Xeon, 512MB, 4x 200GB SATA on 3ware) to
gain the various I/O scheduling improvements, but obviously whether it's
even remotely possible depends primarily on whether NFS is up to it.

I have stock 2.6.5 on a test machine, and am getting *well* under
1MB/sec with bonnie++ over NFS on Gigabit (ttcp gets 18MB/sec, no jumbo
frames), compared to 20+MB/sec local (single old ATA disk).  Haven't
tried to pin down what precisely is causing the issue, but it begs the
question: should I even be considering 2.6's NFS as production-capable
yet?

TIA,
