New submission from Liran Nuna <liran...@gmail.com>: The performance of async/await is very low when compared to similar code that implements similar functionality via iterators, such as Quora's asynq library (https://github.com/quora/asynq/tree/master/asynq).
Based on my benchmarks, asynq is almost twice as fast as async/await. I have found some performance hanging fruit when benchmarking (See attached GitHub PR). $ time python batch_asyncio.py real 0m5.851s user 0m5.760s sys 0m0.088s $ time python batch_asynq.py real 0m2.999s user 0m2.900s sys 0m0.076s ---------- components: asyncio files: batch_asyncio.py messages: 307492 nosy: Liran Nuna, yselivanov priority: normal pull_requests: 4599 severity: normal status: open title: async/await performance is very low type: performance versions: Python 3.6 Added file: https://bugs.python.org/file47313/batch_asyncio.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32204> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
