Thumbor has now been serving all public thumbnail traffic for Wikimedia production since late June 2017.
We are currently in the final stages of deploying Thumbor to Wikimedia production, where it will generate media thumbnails for all our public wikis. Up until now, MediaWiki was responsible for generating thumbnails.
One of the goals of the Wikimedia Performance Team is to improve the performance of MediaWiki and the broader software stack used on Wikimedia wikis. In this article we’ll describe a small performance improvement we’ve implemented for MediaWiki and recently deployed to production for Wikimedia. It highlights some of the unique problems we encounter on Wikimedia sites and how new web standards can be leveraged to improve performance.
As the Wikimedia Foundation’s Performance Team, we want to create value for readers and editors by making it possible to retrieve and render content at the speed of thought, from anywhere in the world, on the broadest range of devices and connection profiles.
