Probably the only thing I'd say was worth fiddling with was the MTU - send some pings go for the highest where the packet doesn't get fragmented but you have to fiddle with the switch and so on. I guess this wasn't your question.

Thanks, I will look into it.  It does look like the Intel NIC made a huge difference.

The switches I have in this particular environment are unmanaged and dumb so I may be
at the limit of this system.
