Fully agreed.

While I trust that you think it's faster I would like an objective way
to measure this on the systems that I care about.

Please provide a microbenchmark that shows this to be the case. That way
we can include it in our regular testing and distributions can ensure
that the performance stays consistent across releases, compilers, etc.

Cheers,
Carlos.
