If you could format (or tune2fs) the ext3 filesystem with "-O dir_index" this would likely improve performance if the test is creating many files in the same dir. Also, is the file size limit in bytes, or kilobytes? Unfortunately, the canonical postmark URLs I can find are not useful. What is a interesting, though maybe not terribly surprising is that ZFS is doing so poorly in the second test. I'd be extremely interested in seeing the vmstat output while the tests are running, as I've heard that ZFS is CPU hungry because of the checksumming.
