All the local cables & hubs are 10baseT (and this is also what autodetect figures out). My connection to the internet is a 2MBit fixed line connection. The problem ist, that all local traffic (inside my subnet) to and from the TX200 machine is very, very slow. Here is what netperf says from TX200 to other FreeBSD machine: www# ./netperf -H 217.6.66.203 TCP STREAM TEST to 217.6.66.203 : histogram Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 57344 32768 32768 14.40 0.07 netperf on both machines using localhost reports normal speed: www# ./netperf TCP STREAM TEST to localhost : histogram Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 57344 32768 32768 10.01 1395.26 Connections to the outer world (internet) from the TX200 are at normal speed. I have tried many things to figure out which might be wrong. I changed from "autodetect" to 10baseT, setting half- or full-duplex, have compared the routing tables of the TX200 with the others - but nothing was wrong. Then I dump(1) the complete machine to tape, and restore(1) it on a older test machine (with other NIC), rebuild the kernel to fit these machine ... and everything was fine, local and outbound traffic was good. Therefor I assume that the Broadcom NIC or the driver has a problem. Any idea how to find out more (buy a new network card ?)
