Code for benchmarks at http://blog.perfectapi.com/2012/benchmarking-apis-using-perfectapi-vs-express.js-vs-restify.js/

express.js

var express = require('express');

var app = express.createServer();

app.configure(function(){
  app.use(express.bodyParser());
});

app.get('/', function(req, res){
  res.send('Hello World\n');
});

app.get('/json', function(req, res){
  res.send({ name: 'Tobi', role: 'admin' });
});

function foo(req, res, next) {
  next();
}

app.get('/middleware', foo, foo, foo, foo, function(req, res){
  res.send('1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890');
});

app.listen(8000);

Perfectapi.md

The perfectapi benchmark used an actual module that uses perfectapi, namely node-sharedmem. This module was chosen because it has no external dependencies, and has very little logic.

Restify.js

var restify = require('restify');

var server = restify.createServer({
  name: 'myapp',
});
server.use(restify.queryParser());
server.use(restify.bodyParser());

server.get('/echo/:name', function (req, res, next) {
  res.send(req.params);
  return next();
});

server.listen(8000, function () {
  console.log('%s listening at %s', server.name, server.url);
});
