Assessing Performance & Scaling Capabilities
We assess the CMS platforms' baseline speed, caching abilities, and capacity to handle high traffic loads.
Benchmarking Default Website Performance
When evaluating CMS platforms, it's important to test performance in a default, low-traffic configuration. This provides a baseline for:
- Page load times: How fast pages load from a cold start and after caching.
- Request counts: The number of requests required to assemble each page. More requests can slow things down.
- Bandwidth needs: Total bandwidth consumed per page. Lighter is better.
For example, on a basic brochure-style site built in WordPress, we might see:
- Page load time: 1.2 seconds
- Requests: 28
- Bandwidth: 1.3 MB
Meanwhile, a comparable Drupal-based site could benchmark:
- Page load time: 1.5 seconds
- Requests: 65
- Bandwidth: 1.9 MB
So while WordPress ekes out a slight performance advantage here, both platforms are reasonably quick for low-traffic sites.
Caching Strategies and Website Optimization
When traffic spikes, caching and optimization becomes critical for performance. Here, platforms like Joomla and Drupal shine over simpler ones like WordPress.
Built-in caching features vary:
- WordPress: Limited native caching. Relies heavily on 3rd-party caching plugins like WP Rocket.
- Joomla: Decent native caching abilities. Also supports plugins like JCache.
- Drupal: Excellent built-in caching and asset aggregation systems.
So while WordPress can be optimized for speed, Joomla and Drupal have a performance advantage out-of-the-box, with fewer dependencies on 3rd-party solutions.
Reliability of Scaling for High-Traffic Sites
When evaluating open source CMS platforms, we also need to examine "success stories" with documented performance at high traffic volumes.
Platforms like WordPress, Joomla and Drupal all have examples of large brands relying on them for millions of monthly visitors. However, Drupal seems to have more very-high-traffic use cases documented.
For example, Drupal powers complex, high-traffic sites like:
- Tesla.com (60+ million monthly visitors)
- Economist.com (26+ million monthly visitors)
- MIT.edu (over 1 billion annual page views)
So while all three platforms can theoretically scale with things like database caching, CDNs, etc., Drupal has more public high-traffic implementations, proving horizontal scalability into the billions of annual pageviews.
