This _looks_ like noise to me.
Some benchmarks went up, some went down. The differential profile shows
random gunk that basically amounts to "my computer is slow" because it's
mostly things that change when the result changes, like:
> 182670 +9.0% 199032 stress-ng.mutex.nanosecs_per_mutex
Does anyone think there's something substantial to chase after here?
