I tried the same thing: Creating took 18.6 seconds, deleting 2.4s. Troughput (dd) is 17.5MB/s. Probably it's significant that the 2,500 .lock files that svn update creates are scattered around the directory tree?

Now this is getting weird. I have retried the experiment with neither softdep nor log, i.e. with a plain old FFS, and that performs as well as or even outperforms WAPL. With both a 5.1_STABLE and a 6.0_RELEASE kernel, on a 16k fsbsize FFSv2, the svn updates takes around 5 seconds with either log
