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?
