> A bigger worry is that async frameworks go a bit wobbly under load. Async should generally be better for throughput because you can complete work items without interruption, whereas context switching will give all threads a chance to make progress. Async will start to have issues once you do any sort of non-trivial processing in the event loop. The irony is most cases employing async are latency-sensitive, not throughput-sensitive.
