Test performance of Express router vs static first

router first.js

var express = require('express')
  , app = express();

app.use(function(req, res, next) {
	var t = Date.now(), end = res.end;
	res.end = function() {
		end.apply(this, arguments);
		console.log(req.path, Date.now() - t);
	};
	next();
});

app.use(app.router);
app.use(express.static(__dirname));


app.get('/test.html', function(req, res) {
	res.end('ok');
});

app.listen(9999);

static first.js

var express = require('express')
  , app = express();

app.use(function(req, res, next) {
	var t = Date.now(), end = res.end;
	res.end = function() {
		end.apply(this, arguments);
		console.log(req.path, Date.now() - t);
	};
	next();
});

app.use(express.static(__dirname));
app.use(app.router);


app.get('/test.html', function(req, res) {
	res.end('ok');
});

app.listen(9999);
