Agreed, but we still need some kind of reproducible result that shows
your patch improved performance. I'm not happy with performance patches
going into glibc without some proof that they made things better.

If you can't show that with the benchmark, and have some other benchmark
numbers, then I might be convinced, but I'd like you to update our
benchmarking results page for 2.18 to describe what you did and what
numbers you achieved.

Thanks.

Cheers,
Carlos.
