Hello Sijmen, this is not something I remember seeing often on the list; to improve your chances of replies beyond "use iperf to test" (there's tcpbench(1) in base) you should at least provide a dmesg(8).
Maybe even use sendbug(1) and have the report go to bugs@ [1]. Could you run -current [2] to see if the problem is still there?
