>We are using Iperf to generate traffic in our 64 bit Linux test
>environment.
>Iperf worked great in our 32 bit environment (SUSE LINUX Enterprise Edition
>8).

>I am running the server and client on the same machine.

>I am seeing the following error on the client side:

>Client connecting to 127.0.0.1, TCP port 5001
>TCP window size: 49.5 KByte (default)
