Apache versus Lighttpd

Since I’ve been running Typo for this blog I’ve been having Apache do a mod_proxy to pass anything bound for fak3r.com to a port that Typo is running on with LightTPD spitting up the pages. I’ve read about how much faster Lighttpd is, but today I wanted to test it out on my own enviroment in the hopes that it would convince me to migrate over, if for nothing else that to learn a new webserver. Well, you can draw your own conclusions from the results, and I’ll update things later. First we run the ApacheBench (packaged with Apache, or available via CPAN - HTTPD::Bench::ApacheBench) benchmarking tool set for 10 concurrent users, each making 1000 requests (so a total of 10,000 requests) with Apache 2.0.55 running. Note that is simply pulling whatever it finds in /:

<code>[13:50:01] [root@pepe ~]# ab -n 10000 -c 10 http://localhost/

And now the same test, 10,000 requests total, but with LightTPD 1.4.9 running the show:

So yes, this just shows Lighttpd kicking ass on pulling a small (1.5K) file over and over, but shows that they have a different approach. I’m going to do some more benchmarking, but want to move my entire webserver over to Lighttpd, and will once I figure out how to fix the Drupal 4.6 not working with lighttpd 1.4, php 4.4. Essentially it fails to find any of the multi hosted ‘sites’ hosted under the same Drupal instance. I currently have 3, but it defaults to ‘default’ making it unable (or unwilling?) to display the other sites. My options are try to fix it, or migrate all the sites over to Typo; both are being considered.
