Don't forget to take into account the time it takes to umount a
softdep partition; (There's No Such Thing As A Free Lunch)
If you check the tech-perform mailing list archives from the last year
or so, you'll details of some benchmarks I was doing to test the
performance improvement of the "new dirpref" code, which I compared
before+after with softdeps as well.
In short, between each run you probably want to umount and remount a
partition, to flush out the buffer cache, etc.
