Hi everyone,
first post here. I wanted to present my performance-focused web server/framework
https://github.com/aerojs/aero which was originally created to easily develop websites in an enjoyable way and later turned into a full server + framework that allows you to get 100/100 PageSpeed easily and on top of that has the fastest routing of all the libraries I tested so far:

It's not fully feature-complete yet but if you'd like to try it for your next project, feel free to give it a ride. I'm using it on 5 sites in production already and the number will be growing.
Currently it only works with Jade and Stylus.
If something is not clear please let me know. I don't consider myself a good writer for documentation but there is some basic documentation on the GitHub page to get started.
Best regards,
Eduard Urbach
