I would also advocate to put it in bench/ and make it use BenchTimer, and if BenchTimer is not good enough then let's improve it.

Also don't forget -mfma on Haswell!

is supposedly fixed in VS 2015.

Can't we simply use bench/BenchTimer.h for this?

And even if this is experimental code, I'd prefer having this in the repository rather than sending different versions by mail.

Eventually, this might even be a starting point for performance-oriented unit-tests.
