Mobile web performance: the importance of the device
Let’s explore our web performance data from an angle we haven’t explored before: mobile device type.

Thumbor support for private wikis deployed
Yesterday we deployed Thumbor support for Wikimedia-hosted private wikis. While 99.9% of our traffic is for public-facing wikis, the Wikimedia Foundation hosts a number of private MediaWiki instances on the same infrastructure.
Measuring Wikipedia page load times
Here is how we measure and interpret load times on Wikipedia. Let’s also look at what real-user metrics are, and how percentiles work.
The journey to Thumbor, part 3: development and deployment strategy
Introducing Thumbor replaces an existing service, and as such it’s important that it doesn’t preform worse than its predecessor. We came up with a strategy to reach feature parity and ensure a launch that would be invisible to end users.
The journey to Thumbor, part 2: thumbnailing architecture
To understand why Thumbor is a good fit, it’s important to understand where it fits in our overall thumbnailing architecture. A lot of historic constraints come into play, where Thumbor could be adapted to meet those needs.
Improving time-to-logo performance with preload links
Thanks to a new web standard, we’ve recently deployed a small performance improvement that highlights some of the unique challenges we encounter on Wikimedia sites.
The journey to Thumbor, part 1: rationale
Making Thumbor production-ready for Wikimedia is a journey that started a year and a half ago. Let’s look at the rationale for this project.
Looking back: improvements to edit save time
Is it faster to save articles on Wikipedia than it was a year ago?
Investigating a performance improvement
When a performance improvement seems too good to be true, it’s time to investigate in depth and find out what happened.
How we made editing Wikipedia twice as fast
Over the past six months we deployed a new technology that sped up Wikipedia’s backend application, reducing the median page-saving time for editors from about 7.5 seconds to 2.5 seconds.
