This particular patch? No. As for the whole series, Jens has done the best actual benchmarks; mostly I've just been looking at profiles - I don't have any high end hardware with drivers suitable for that kind of benchmarking, myself.
Also, my changes have been particularly aimed at improving the situation where an ioctx is shared between different threads; we don't have any actual benchmarks for how much that's improved as fio doesn't do that but the gains there are going to be much more significant, for applications where that's useful.
