I feel it necessary to clarify that I am not suggesting we should use single-threaded servers. My go-to approach for one-offs is Go HTTP servers and reverse proxying. This will do quite well to utilize multiple CPU cores, although admittedly Go is still far from optimal.

Still, even when people run single-thread event loop servers, you can run an instance per CPU core; I recall this being common for WSGI/Python.
