I've tested a particular python webserver in PyPy and saw roughly the same performance as CPython on average. My guess at the time was that PyPy has a bigger overhead for network sockets than CPython. You would likely see a gain from using PyPy if the webserver did heavier processing in pure python than what mine does.

I’m not sure it’s worth to invest too much effort in such optimisations unless they can yield perceived performance improvements or cost reductions. For Google, a 0.1% decrease in power consumption pays for itself in hours, but for mere mortals (and regular companies) it often doesn’t.

It’s a fun sport though. I love it.

I just wanted to make sure I wasn't passing up on a free 400% boost or something :-) but it was already running plenty fast, so it was entirely out of curiosity.
