I'll look into 2.4.20, as for the hidden patch, it has no affect.  I
checked that out right at the beginning.  I thought originally that it was
the problem.

If you are seeing 30Mbit/s on a Gigabit connection, then my vote still
goes to packet loss. I'm seeing ~25MByte/s on writes against a filer
when using 2.4.19 (and about 40MByte/s on reads).

I'm only using 30 Mb/s because that is what the service currently needs,
it's not a limitation.  I was able to create a 250Mb/s load through the
card to the filer.  Would I not get the same behaviour if the card was the
problem?

Depends entirely on how you did your test. If you used UDP with 32k message
sizes, then the 2 should indeed be comparable. If not, ....

Kernel is 2.4.18 and .config is attached.  Note that I've added LVS
group's hidden patch for direct routing (DR) load balancing.

Try 2.4.20. It has a much improved UDP congestion control.

No idea what your load balancing patch will do, but I suggest that you compare
with and without.
