Brooks,
Actually I use the freebsd box as an router. I set the tcp window in
another two windows box running iperf (iperf -w 5M).
Before I add in the pipes, the throughputs could reach 300M, but after
I config in the two pipes(200M bandwidth, 25ms delay), the throughput
degrade to about 5M.
BTW, is there some limitations to tcp connections passing through a
router?
Thanks,
