Gevent + Requests Performance With verify=True/False

11 Aug 2017 If you use gevent with requests.get on a HTTPS URL with the default verify=True enabled, you'll see almost 2x longer execution times than with verify=False.

I made a script to test: https://gist.github.com/pawl/56100a4ef958374a433840be8037b11b

Here are the results:

verify=True took: 40.3454630375 secs
verify=False took: 39.3803040981 secs
gevent verify=True took: 2.23735189438 secs
gevent verify=False took: 1.58263015747 secs

I suspect that gevent is having trouble using pyopenssl concurrently because it's a C library.
