RE: FTP Conundrum with Communication Trace

[Dwayne Lindner <Dwayne.Lindner@xxxxxxxxxxxxxxxxxxxxxx>]

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...
