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?
