Seriously, it's amazing. It's like gevent, but with better documentation.

I was under the impression that gevent was like a new version of eventlet. Other than the docs (which isn't insignificant), why choose one over the other?

They're pretty similar. The main difference is that Eventlet supports more event loops, has a messier basic architecture, is slightly slower, and lets you defer blocking tasks to threads. Since I'm connecting to MySQL, which happens through blocking C code in libmysql, that's pretty important to me. Eventlet's db_pool module is very nice.

Personally, I'm happy with eventlet and can't see why I would want to go to gevent. Does anybody using gevent want to chime in on what's better about it?

gevent has utilities to turn Python blocking calls into non-blocking ones.

In your case you could switch to a pure Python MySQL driver and gevent will turn all your mySQL calls into async.

Actually there're also gevent non-blocking MySQL drivers that are written in C.
