Highest performance [benchmarked] "HTTP microframework"?

[Alec Taylor]

E.g.: using Cython

I am currently using Bottle, and it's fine; but provides much more than I need.

Investigating rewriting in C++; perhaps using restcgi. Can give that
restcgi a bit of a rewrite, removing the boost dependency and
replacing it with a C++11 dependency.

However given the lack of a "neat" ORM in C++ with a large variety of
backends (like SQLalchemy has); I would be leveraging boost::Python or
similar.

So maybe I should give Python another chance? - What's the highest
performance Python "HTTP microframework" capable of routing with
decorators?

Thanks for all suggestions,
