Ummm ... you forgot to mention Postgres version? Also, which client and
server encodings did you use (that starts to get to be a noticeable
issue for high COPY rates)?

Right. For small transactions with a drive honoring fsync, you should
expect to get a max of about one commit per platter revolution. Your
numbers work out to a shade under 5000 commits/minute, from which I
speculate a 7200 RPM drive ... do you know what it really is?
