A proof of concept of having Sinatra like routes inside your controllers.

How to use

Since the router is gone, feel free to remove config/routes.rb. Then add the file below to lib/action_controller/inline_routes.rb inside your app.

Comparative Benchmark Numbers @ Rackspace

I've taken the benchmarks from Matthew Rothenberg's phoenix-showdown, updated Phoenix to 0.13.1 and ran the tests on the most powerful machines available at Rackspace.

Results

Framework	Throughput (req/s)	Latency (ms)	Consistency (σ ms)

Lies, Damned Lies and Benchmarks

This is just an exercise to measure the performance between Sinatra-like libraries in:

• Elixir v0.4.dev (running on top of the Erlang VM R14B03) with Dynamo;

• Ruby 1.9.2 with [Sinatra Synchrony] v0.0.3 (https://github.com/kyledrake/sinatra-synchrony) + Thin;

• node.js 0.4.7 with [express] v2.3.10(https://github.com/visionmedia/express)

// Improvements to file uploads with Zombie.
//
// Just start the Sinatra server below and run this file with node.
// Depending on the server used with Sinatra, it will fail upfront or forward
// a bad request to the app. The source code in zombie is in the link below
// (you will need Zombie from git, you can check it out and use `npm link`):
