Jesse Wilson commented on HARMONY-6434:
---------------------------------------

Perhaps you could create some benchmarks to demonstrate the performance benefits of your implementation?

You can use Caliper for single-threaded benchmarks if you like:

Amino Library, which has better scalability than original queue
