Benchmarking Apache 2 vs. Lighttpd

Have you ever wondered which is faster, Apache 2 or Lighttpd? Everyone says that Lighttpd (or lighty) is a much faster, but is it really so?

I found this curious article I'd like to share with you. It can be originally be found here but I'm also going to write a short version about the article below:

The benchmark shows how Apache 2.2.3 compares to Lighttpd 1.4.13 when delivering static HTML file approx 50 kilobytes. Test was made with Apache benchmark.

The test was made on a Debian Etch running inside VMware. The box was quite old but it shouldn't affect on the tendency.

Versions were:

*Apache 2.2.3 mpm-prefork with default Debian configuration.
*Lighttpd 1.4.13 with default Debian configuration.

The HTML file was approx 50 kilobytes in size and it was saved as test.html.

I've run the following commands ten times each and calculated the average requests per second that the web server could handle:

*ab -n 100 -c 5 http://localhost/test.html
*ab -n 1000 -c 5 http://localhost/test.html
*ab -n 10000 -c 5 http://localhost/test.html
*ab -n 100 -c 50 http://localhost/test.html
*ab -n 1000 -c 50 http://localhost/test.html
*ab -n 10000 -c 50 http://localhost/test.html
*ab -n 100 -c 100 http://localhost/test.html
*ab -n 1000 -c 100 http://localhost/test.html
*ab -n 10000 -c 100 http://localhost/test.html

-n is the number of requests to perform for the benchmarking session; -c is the number of multiple requests to perform at a time.

Here's result of the test:



As you can see, lighty is almost one third faster on static pages! Knowin this one has to consider if it is worth using lighty instead of Apache. Personally I choose Apache? Why? More modules and knowledge. Maybe some day I'll start using Lighty. Or Nginx. Woudln't that be kewl?
