Here's something that _might_ interest xfs folks.
cd git (source repository of git itself) make clean echo 3 > /proc/sys/vm/drop_caches time make -j8 test
ext4 2m20.721s xfs 6m41.887s <-- ick btrfs 1m32.038s tux3 1m30.262s
Testing by Aunt Tilly: mkfs, no fancy switches, mount the thing, test.
Are defaults for mkfs.xfs such that nobody sane uses them, or does xfs really hate whatever git selftests are doing this much?
