Wow, from 695 requests per second to 49,516 is a huge improvement! Since we were comparing to django previously, it's now much closer with django (which does 78,132 rps.)
Django also does run multiple worker processes (3 per cpu): https://github.com/TechEmpower/FrameworkBenchmarks/blob/master/frameworks/Python/django/gunicorn_conf.py#L8 The other tests are also doing much better. So do I undestand correctly that the factors that contribute to the improvement are: 1. running multiple worker processes behind nginx 2. adding content-length to all responses 3. using CS variant of Racket 4. using Racket 7.7 5. tuning nginx config (enabling http 1.1 especially) I'm curious what was the individual contribution of these factors. In the PR regarding #5 you already stated that it gives a 4-5x improvement. #1 and #5 are the things one would normally do anyway in a production setup I guess. As is #4 most likely. #2 is something that seems to require manual work in the client code, but maybe that can be made easier on web-server-lib side somehow. Curious how much do #3 contribute. Big thanks again for everyone investing time in investigating this. -- Yury Bulka https://mamot.fr/@setthemfree #NotOnFacebook Bogdan Popa <bog...@defn.io> writes: > Small update on this: I've updated the benchmarks to run multiple Racket > processes with an Nginx load balancer in front.
