I've done measurements on the patched kernel. All that remains is to do
measurements on the baseline unpached case. To summarize the results
thusfar,
Times:

Altogether, it seems that something is horribly wrong, most likely with
my test (or rsync patch). I'll do the baseline benchmarks today.
Thoughts?
Thanks,
