Woot!  2.7MB/s -> 76MB/s

Is this a FAQ somewhere?  I spent a long time looking
today and didn't find it (I do recall seeing a mention
of TSO but not seeing how to do it or that it fixed
the problem)

On the second suggestion:

root at feyerabend> sysctl -a | grep dev.em | grep enable_
root at feyerabend>

No problem, though.  76MB/s is A-OK.

Thanks!  I'm very happy now.
