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.
