The benchmarks mentioned about async rust being slower are from a bad implementation from someone who had never programed much rust before. You can write any program in any language to be slow. It is unlikely that go would be much faster if it is at all.
WebbTake a look at the WorkStealingQueue class which implements the work stealing queue as described in the paper "Dynamic Circular Work-stealing Deque," SPAA, 2015. The structured_task_group class of the PPL uses a work stealing queue for its implementation. If you need a WSQ for threading, I would recommend that.
