Sinatra

ruby 1.9.2 + async_sinatra + thin thin start

ab -n 10000 -c 100 http://localhost:3000/
-> 49ms / request

Node

node server.js

ab -n 10000 -c 100 http://localhost:3000/
-> 20ms / request

config.ru

#!/usr/bin/env
require 'sinatra/async'

class AsyncTest < Sinatra::Base
  register Sinatra::Async

  aget '/' do
    body "hello async"
  end
end

run AsyncTest.new

server.js

// Load the http module to create an http server.
var http = require('http');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  response.writeHead(200, {"Content-Type": "text/plain"});
  response.end("Hello World\n");
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(3000);

// Put a friendly message on the terminal
console.log("Server running at http://127.0.0.1:8000/");

Or you could go the other way and benchmark a straight Rack "Hello World" application.

feel free to fork :)

With ruby 1.9.3 I got about 98ms with ruby and 21ms with node 0.6.18
