really popular portals, news sites? yes. really popular websites? 
nope. like booking.com, airbnb.com, reddit.com are popular 
websites that have many parts which have to be dynamic and 
responsive as hell and they cannot use caching, pre-generated 
content, etc.

using python affect the performance of your website. if you were 
to use ruby or php your web app would be slower than it's python 
version. and python version would be slower than go or d version.
