This is a recording of a presentation I gave at Drupal Gov Day called Purespeed. There’s many posts on this site that are tagged with purespeed if you want to dig into deeper detail about anything mentioned in this talk. This talk consolidates a lot of lessons learned in optimizing drupal to power elms learning network. I talk through apache, php, mysql, front end, backend, module selection, cache bin management, and other optimizations in this comprehensive full-stack tuning talk.
