Which Python3 framework to choose for a REST application?

Question

Python

Help me choose a framework for a REST application. The framework should support Python3, be high-performance (many small but frequent requests), have good documentation (preferably in Russian).
The main task of the application is to display small pictures and information in JSON format (most often from the cache).
I would be glad to see tips on choosing, links to comparisons of frameworks, usage statistics and other information.

Answer 1

Personally, I like Tornado, it was written just for "a large number of small, but frequent requests." If the developers do not lie. The framework is light, the docks are not bad (in Russian, however, I did not find it).
