Gatsby sites are renowned for their speed, and efforts to enhance the Gatsbyjs.com homepage focused on improving its Lighthouse score, a well-known performance metric by Google, which aggregates scores from web vitals. The team identified Time to Interactive (TTI) and Total Blocking Time (TBT) as key areas for improvement and conducted various experiments, such as optimizing font loading, reducing excess code, and disabling offscreen animations. These efforts resulted in a score increase of 22.8 points. Although some experiments, like using the content-visibility CSS property, didn't yield the desired results, the process led to valuable insights and improvements that could benefit the wider Gatsby ecosystem. The team aims to incorporate these lessons into Gatsby's core framework, exploring further enhancements like deferred script initialization and better code bundling, particularly following the upgrade to webpack 5, which significantly reduced the homepage's load size. While acknowledging room for improvement, particularly for mobile users, the team is committed to making Gatsby sites even faster and more efficient, with plans to help other Gatsby sites achieve similar performance gains.
