Gatsby Days 2020 in Los Angeles featured a series of presentations aimed at sharing insights and best practices with the Gatsby community. One highlight was Grant Glidewell's talk on improving website performance using Gatsby Builds, where he showcased how his team at Third and Grove significantly reduced build times for their image-heavy site from 40 minutes to just 8 by integrating Drupal with Gatsby. Glidewell emphasized the use of Gatsby's lazy load components to enhance performance without requiring excessive coding. The event, which also shared updates on upcoming virtual events and registration details, provided valuable resources for developers looking to optimize their Gatsby-based projects.
