> But if you are using a global lock what real concurrency are you actually getting? I suspect most of the time the threads will be blocked waiting for that mutex and so the whole thing will degenerate into an expensive form of serialization. Have you tried a simple benchmark using (say) a couple of compute-bound for loops to see how much faster they run vs a single loop?
Yes, there's currently no concurrency when executing a lua function so work done
in multiple threads isn't faster than if it's done sequentially. However
