Yes, it does (~26000000 bytes). I have two further GigE-equipped OpenBSD boxes on the LAN and they top out at a plausible ~95Mbit/s when UDP streaming to the same target. However, netperf also reports a large number of errors (dropped packets?) in their case--but actual netstat interface figures again concur with the throughput. Alas, I have no further FreeBSD boxes to test this. -- Christian "naddy" Weisgerber naddy@mips.inka.de
