No.  I can't get the remote computer to boot over NFS using jumbo frames.
I have no idea how to (modify the boot image?) make that happen.

That being said, even at an MTU of 1500, netperf reports decent 
throughput.
If you want to know the value - hmmf, I'd just don't remember and will 
have to
run it again...  780,000,000 bits per second sticks in my mind...

If I got 50% of netperf, I'd be happy...  Heck, 33% would be good...

This is on a local network, only thing running (that I know of)is nfs and 
my app.
