TTCP

Does anyone know the proper settings for using Test TCP (TTCP) over a gigabit fiber link? I want to bench test some circuits, but the only model I have to work from is a demo sheet illustrating a 56Kbps TTCP test. I'm having trouble figuring out how I need to set my NBUF, BUFLEN, and RCVWNDSIZE settings for testing gig. Any suggestions?

Re: TTCP

The following gives decent results: nbuf=90000, buflen=1400. RCVWNDSIZE is relatively arbitrary in this example.
