Node.js powers comet for plurk (100k+ users at once)

Also I would like to note I saw your Tornado vs Node.JS hello world test and it made me curious because we use Tornado and we really believed that it was the fastest.

So I looked at your results and noticed Tornado had 100x more bytes transfered in your AB test. So I decided to run your same test on a raw Tornado HTTP server (not using the web.py framework) and these were the results of Hello World.

These tests were ran on an 3.66 i7

Tornado (single instance):

import tornado.httpserver import tornado.ioloop

def handle_request(request): message = 'Hello Word' request.write("HTTP/1.1 200 OK\r\nContent-Length: %d\r\n\r\n%s" % ( len(message), message)) request.finish()

http_server = tornado.httpserver.HTTPServer(handle_request) http_server.listen(8009) tornado.ioloop.IOLoop.instance().start()

ab -c 100 -n 4000 http://127.0.0.1:8009/ Requests per second: 10037.84 [#/sec] (mean)

Node.js (single instance):

var sys = require('sys'), http = require('http'); http.createServer(function (req, res) { res.sendHeader(200, {'Content-Type': 'text/plain'}); res.sendBody('Hello World'); res.finish(); }).listen(8008);

ab -c 100 -n 4000 http://127.0.0.1:8008/ Requests per second: 9159.65 [#/sec] (mean)

However doing the test the way you did it did show the results you had with Tornado being 2x slower, however I don't believe that was a fair test at all.

Just my input.
