Node.js versus IIS 7.5 performance

Question

Setup:

2 cars on EC2 type m3.xlarge.

First with the ubuntu server.

The second option is win2008r2.

ubuntu node.js using a basic example to return a string response to any request.

asp.net httphandler to return the same answer.

using https://github.com/newsapps/beeswithmachineguns I used 10 machines to run 200,000 with concurrency 2000 (200 per machine) I ran a test and got:

NodeJS:

Complete requests: 200000 Requests per second: 5605.170000 [#/sec] (mean) Time per request: 358.071900 [ms] (mean) 50% response time: 31.000000 [ms] (mean) 90% response time: 239.300000 [ms] (mean) 

IIS:

  Complete requests: 200000 Requests per second: 9263.810000 [#/sec] (mean) Time per request: 215.992900 [ms] (mean) 50% response time: 214.000000 [ms] (mean) 90% response time: 244.000000 [ms] (mean) 

NodeJS code:

 http.createServer(function (request, response) { response.writeHead(200, {'Content-Type': 'text/plain'}); response.end('Some response\n'); }).listen(80); 

Httphandler code:

 context.Response.Write("Some response\n" + Guid.NewGuid().ToString("N")); 

I thought node js would be much faster, did I do something wrong?

EDIT:

after using the cluster module i got 16685 requests per second from node js i'm going to output the strongest instances of EC2 and check them

Answer 1

The m3.xlarge instance has several processor cores, while node.js is single-threaded. You can try comparing the cluster node.js module and see if using more CPU helps. And, since node.js is completely new, be sure to use the latest stable series (0.8.x at the time of this writing).
