Maybe, but I'm not convinced that's correct. You are gaining, because you don't
then have to deal with the overhead of opening and sending information over
sockets. I'm writing my code in C exactly because it's aimed towards very
high-load servers, and I'd rather avoid any extra overhead if possible.
The architecture is there for it to work just fine within Nginx, I just don't
know how yet. Also, there's a lot of code withing Nginx that I'd have to
reproduce in order to run it in its own binary.
If ultimately my code ends up destabilizing Nginx, then I would move it out into
its own process, but I want to try to get it working without doing that first.
