So use multiple processes with SO_REUSEPORT then. Or find yourself a wsgi server that does, because it's not exactly an unsolved problem. That said by far most programs don't need to worry about saturating a 10G connection. I'm not writing a file server in python, I'll leave that to nginx or S3. I'm writing business logic in python which tends to be bottlenecked by a database in any case. Python is great for plumbing together other functionality, which it turns out means most backends you'd be writing anyways. Python is less great at handling a large quantity of data, though most of the time you can get away with handing the data handling to some library (e.g. numpy or libuv or any one of thousands of libraries). Worst case you can easily plumb in some C-calling-convention code into python. With FFI it's a matter of copying the header definition and you're off to the races. That way you can still write the bulk of the program in python, delegating the bulk data wrangling to C or D or rust or go or whatever you prefer.
