Phalcon vs. Kohana vs. Padrino

Phalcon is a web framework implemented as a C extension offering high performance and lower resource consumption.

Kohana is an elegant, open source, and object oriented HMVC framework built using PHP5, by a team of volunteers. It aims to be swift, secure, and small.

Padrino is a ruby framework built upon the excellent Sinatra Microframework. Padrino was created to make it fun and easy to code more advanced web applications while still adhering to the spirit that makes Sinatra great!
