very small and do not contain any routing logic like other implementations. Nonetheless, this benchmark demonstrates how quickly uvloop and an efficient protocol can be combined.7th paragraph (1.39 points can be obtained)Banna 9 months agoConclusionWe can conclude that using Uvloop can write Python network code that can make tens of thousands of requests per second in a single CPU core. Under multi-core systems, you can use process pooling to further improve system performance.Uvloop and Asynci
