Do you have the ports on the Cisco set to full duplex or auto-sensing?

| Interestingly, we have three machines with 2838's connecting to a
Cisco
| 6509
| switch (one of the BIG ones).
|
| The machines achieve extremely poor throughput when set to full duplex
-
| half duplex has been the only way to get decent performance out of
them...
