Ok, try my second version. The first version would get _some_ parallelism, but very little due to all the threads often trying to just look up in the same directory. The second version should hopefully have less of that effect.

Also, under Linux, try it with caches cleared in between runs, so that you can avoid any issues of the Linux client caching the directory lookup data (which linux _will_ do - I think the default timeout is 30 seconds or something like that):

	echo 3 > /proc/sys/vm/drop_caches ; time git diff

which should hopefully get you more reliable timings.
