Program ended with exit code: 0Comparing PlayRho timing data to Box2D timing data looks surprising if not downright odd. Are tests like AddPairStressTestPlayRho400 and AddPairStressTestBox2D400 supposed to be comparable? I thought they were. The data however, at least for cases like AddPairStressTestPlayRho400/18 compared to AddPairStressTestBox2D400/18, don't appear comparable at all when looking at times of 1,120,420 ns (for PlayRho) vs. 104,630,145 ns (for Box2D) - PlayRho appears to be 100 times faster. That'd be great news to me if so but I'm not ready to bet on that being a proper interpretation of these results.
Data since update to Benchmark code (to do 1000 ops per loop etc to increase Time and comparative sensitivity):

Program ended with exit code: 0This dump includes some new benchmarking I'm trying out: AsyncFutureDeferred, AsyncFutureAsync, ThreadCreateAndDestroy, and MultiThreadQD.
Basically the output shows 13942 ns to be a minimum of delay incurred by synchronization via mutexes and condition variables. That's like the equivalent of over 6000 floating point divisions.
Presumably spin locks would be faster but waiting threads would be spinning a significant portion of their time. That might well tank performance then in other ways. I'll be looking into it though.
