Mathias Agopian	cfb9c03226	Improve JobSystem, especially under contention ... - only signal waitAndRelease() when the corresponding job finishes and only if there is waitAndRelease() active -- instead of signaling every time a job ends. - don't surrender time slice when attempting to steal a job and it fails as long as some queue has jobs. - check that we have to wait, because taking the lock - add a benchmark This change more than doubles the amount of jobs we can handle per second (~965,000 jobs/s on Pixel3)	2018-12-14 16:01:17 -08:00
Mathias Agopian	e8895fee11	Add a binary search benchmark ... this one basically shows that the stl is is a good as our "branch less" versions. this is because clang generate branchless code in the end.	2018-11-29 11:44:52 -08:00
Mathias Agopian	785ce645e2	pool allocators benchmark ... this benchmark shows that, as we expected, on Android mutexes, spinlocks and lock-free algorithms are running at similar performance.	2018-11-29 11:44:52 -08:00
