Drupal vs Joomla: performance | Dries Buytaert

 
Dries setup an experiment to benchmark drupal and joomla in a couple of scenarios.

 One test that stood out was that in his test, "Joomla's cache system improves performance by 12%".  Only 12%? This does not seem typical in my experience when caching with Drupal and phpSlash.  Anybody familiar with Joomla that can confirm or investigate?

Which content management system is faster? Drupal or Joomla?

I used the "Apache, mod_php, PHP4, APC" configuration from previous benchmark experiments to compare the performance of Drupal and Joomla on a 3 year old Pentium IV 3Ghz with 2 GB of RAM running Gentoo Linux. I used the following software: Apache 2.0.55, PHP 4.4.2, MySQL 4.1.4, Drupal 4.7.3 and Joomla 1.0.10.

I simply downloaded and installed the latest stable release of both Drupal and Joomla, and tried my best to make them act and look the same. To do so, I enabled the login form and the "Who's online" block. I also setup two links and a search widget in the top menu, enabled the hit counters for posts, and setup identical footers. Next, I created one author, one category and one post as shown in the images below.

Apache's ab2 was used to compute how many requests per second both systems are capable of serving. The page was requested 1000 times with a concurrency of 5 (i.e. ab2 -n 1000 -c 5). To test the impact of gzip-compressing pages we specified whether ab2 can accept gzip-compressed pages (i.e. ab2 -n 1000 -c 5 -H "Accept-Encoding: gzip;"). Note that ab2 did not request any images or CSS files; only the dynamically generated HTML document was retrieved.
