the box is a bit old (Intel Pentium III (933.07-MHz 686-class CPU) dual cpu. running iperf -c (receiving): freebsd-4.10 0.0-10.0 sec 936 MBytes 785 Mbits/sec freebsd-5.4 0.0-10.0 sec 413 MBytes 346 Mbits/sec freebsd.6.1 0.0-10.0 sec 366 MBytes 307 Mbits/sec freebsd-6.2 0.0-10.0 sec 344 MBytes 289 Mbits/sec btw, iperf -s (xmitting) is slightly better freebsd-4.10 0.0-10.0 sec 664 MBytes 558 Mbits/sec freebsd-5.4 0.0-10.0 sec 390 MBytes 327 Mbits/sec freebsd-6.1 0.0-10.0 sec 495 MBytes 415 Mbits/sec freebsd-6.2 0.0-10.0 sec 487 MBytes 408 Mbits/sec so, it seems that as the release number increases, the em throughput gets worse - or iperf is. danny
