A few months ago I tested my local network speed with iperf and got around 900Mbits/s. But with a newer current I get around 300Mbits/s, (using 100% cpu usage), and to localhost: 162 Mbits/sec. I'm running iperf -s in one terminal and iperf -c localhost on another. FreeBSD 7.0-CURRENT #9: Mon Jul 9 13:18:23 CEST 2007 root@fs:/usr/obj/usr/src/sys/FS i386 Stock kernel, but removed debuging and witness, and using SCHED_ULE. Not knowing where to look I tried to update. Recompiled with updated source and with SCHED_4BSD: FreeBSD 7.0-CURRENT #9: Mon Jul 9 13:18:23 CEST 2007 root@fs:/usr/obj/usr/src/sys/FS i386 Same problem, am I missing something obvious here?
