Hi Doug,

have you ever tried netio to check for raw needwork speed?
http://www.ars.de/ars/ars.nsf/docs/netio
It does not add any overhead caused by file operations - so it
can help to tune raw parameters.
The source is included - so it can be tuned, too.
When sniffing such traffic, also have a look, how tcpi/ip ACK
packets are used and whether they are send immediately
or with some delay.

Good luck - Guenter Kukkukk
