A good python web server should be single process with asyncio , or maybe have a few worker threads or processes. Definitely not fork for every request
Your response explains the other one, which I found just baffling.
I didn't say forking per request, good god. I meant running a process per core, or some ratio to the cores to achieve full server utilization. Limiting all of HTTP/2 requests per user to one core is unlikely to result in good feelings for anybody. If you let nginx fan them out to a couple cores it's going to work better.
