So input speed is reasonable but write throughput is miserable--<10MB/s. I'd suggest taking this to one of the FreeBSD lists; this doesn't look like a PostgreSQL problem.
This is on FreeBSD 7.0-Release. I tried ULE and 4BSD schedulers with no difference. Maybe I'll try FreeBSD 6.3 to see what that does?
The other thing you might consider is booting with a Linux live CD/DVD (something like Ubuntu would work) and running bonnie++ from there to see what you get. Help to sort out whether this ia a server problem or an OS one.
