Hmm, someone is misreading the results.
I've reread multiple times, and I see a difference of 12s, not .12s.

---> real	0m12.645s
---> user	0m0.003s
---> sys	0m0.159s

And 12 seconds (elapsed, with 0.159s system) means 12s/5000=2.4ms
which could only be explained with the auditing system doing fsync
calls on its log files.
