​​In recent years, instagram.com has seen a lot of changes — we’ve launched stories, filters, creation tools, notifications, and direct messaging as well as myriad other features and enhancements. However, as the product grew, one unfortunate side effect was that our web performance began to suffer. Over the last year, we made a conscious effort to improve this. Our ongoing efforts have thus far resulted in almost 50% cumulative improvement to our feed page load time. This series of blog posts will outline some of the work we’ve done that led to these improvements.
