Funny how in the TechEmpower Web Framework Benchmarks[1], the async frameworks are basically destroying their sync counterparts.
They also misleadingly de-emphasise latency variation. One Python async framework I'd never heard of was top of the pops on throughput there even though the latency numbers suggested it had pretty much fallen apart in the test.
The takeaway of this article is that python’s async io implementations perform poorly.
That’s surprising, since async I/O is usually used for performance reasons, and in most other languages, async I/O can be much faster.
