To add further information, it now appears to be caused by the sis
driver. Here is iperf tests with a net4801+sis(4) and pentuim3+xl(4)
using the above pf config.
xl driver
[ 4] 0.0-13.2 sec 200 KBytes 124 Kbits/sec
[ 4] 0.0-23.1 sec 352 KBytes 125 Kbits/sec
[ 6] 0.0-32.7 sec 496 KBytes 124 Kbits/sec
sis driver
[ 4] 0.0-49.8 sec 296 KBytes 48.7 Kbits/sec
[ 6] 0.0-49.7 sec 296 KBytes 48.8 Kbits/sec
[ 4] 0.0-49.6 sec 296 KBytes 48.9 Kbits/sec
