I just did some quick and dirty checks with netperf and noticed a somewhat surprising result. Machine A: Alpha PC164, FreeBSD 5.2-CURRENT, re(4), 1000Base-T Machine B: Alpha PC164SX, OpenBSD 3.5, de(4), 100Base-TX Switch: StarChip SGS-1008 (10/100/1000Base-T) Running netperf -t UDP_STREAM on machine A with target B reports a throughput of ~200(!) Mbit/s. How does the machine get the idea it is pushing 200 Mbit/s down a 100 Mbit/s link? -- Christian "naddy" Weisgerber naddy@mips.inka.de
