Your directories look small and simple, and clearly the indexing made no difference. See earlier email about using "strace -T" instead of "-tt".

I've actually often wanted to have a 'strace' that shows page faults as special system calls, but it's sadly nontrivial ;( Linus -- 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
