After redoing this test with "echo 3 >/proc/sys/vm/drop_caches" (which also discards metadata, as pointed out by Linus), the cold-cache timings are: svn 12.65 seconds git 10.3 seconds So no Earth-shattering difference, but now git is somewhat quicker than Subversion at everything I tested. --Pete -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
