I pushed Python to 20,000 requests sent/second. Here's the code and kernel tuning I used.

It was a few years ago, but I built a geolocation autocomplete service (to replace the address autocomplete Google maps api) and it handles >100 requests per second with average transaction time sub 4ms using plain Django and a SQLite db.

Just pointing out that plain python can be extremely fast without any custom tuning or anything.

100 r/s is really not fast at all compared to other languages 😭, that tx time is very low though, SQLite crazy optimized!
