Help with a performance issue

[Ben Howard]

The short story is that we are seeing profound differences between UFS and
ZFS in terms of network to disk writes.

# FreeBSD with ZFS
$ fetch http://speedtest.bahnhof.se/1000M.zip
1000M.zip 27% of 1000 MB 11 MBps 01m00s

# Stock FreeBSD in NYC3 with UFS:
$ fetch http://speedtest.bahnhof.se/1000M.zip
1000M.zip 1% of 1000 MB 529 kBps 32m12s

The test case is flaky, unfortunately.  Switching the backing filesystem,
IMHO, should not illicit such a massive difference.

Any ideas?

Thanks,
Ben
