    text
    copied!<p>I am comparing performance of Node.js (0.5.1-pre) vs Apache (2.2.17) for a very simple scenario - serving a text file.</p> <p>Here's the code I use for node server:</p> <pre><code>var http = require('http') , fs = require('fs') fs.readFile('/var/www/README.txt', function(err, data) { http.createServer(function(req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}) res.end(data) }).listen(8080, '127.0.0.1') } ) </code></pre> <p>For Apache I am just using whatever default configuration which goes with Ubuntu 11.04</p> <p>When running Apache Bench with the following parameters against <strong>Apache</strong></p> <pre><code>ab -n10000 -c100 http://127.0.0.1/README.txt </code></pre> <p>I get the following runtimes:</p> <pre><code>Time taken for tests: 1.083 seconds Complete requests: 10000 Failed requests: 0 Write errors: 0 Total transferred: 27630000 bytes HTML transferred: 24830000 bytes Requests per second: 9229.38 [#/sec] (mean) Time per request: 10.835 [ms] (mean) Time per request: 0.108 [ms] (mean, across all concurrent requests) Transfer rate: 24903.11 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.8 0 9 Processing: 5 10 2.0 10 23 Waiting: 4 10 1.9 10 21 Total: 6 11 2.1 10 23 Percentage of the requests served within a certain time (ms) 50% 10 66% 11 75% 11 80% 11 90% 14 95% 15 98% 18 99% 19 100% 23 (longest request) </code></pre> <p>When running Apache bench against <strong>node</strong> instance, these are the runtimes:</p> <pre><code>Time taken for tests: 1.712 seconds Complete requests: 10000 Failed requests: 0 Write errors: 0 Total transferred: 25470000 bytes HTML transferred: 24830000 bytes Requests per second: 5840.83 [#/sec] (mean) Time per request: 17.121 [ms] (mean) Time per request: 0.171 [ms] (mean, across all concurrent requests) Transfer rate: 14527.94 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.9 0 8 Processing: 0 17 8.8 16 53 Waiting: 0 17 8.6 16 48 Total: 1 17 8.7 17 53 Percentage of the requests served within a certain time (ms) 50% 17 66% 21 75% 23 80% 25 90% 28 95% 31 98% 35 99% 38 100% 53 (longest request) </code></pre> <p>Which is clearly slower than Apache. This is especially surprising if you consider the fact that Apache is doing a lot of other stuff, like logging etc.</p> <p>Am I doing it wrong? Or is Node.js really slower in this scenario?</p> <p><strong>Edit 1</strong>: I do notice that node's concurrency is better - when increasing a number of simultaneous request to 1000, Apache starts dropping few of them, while node works fine with no connections dropped.</p>
