Hi @mbhebsgaard,
Understanding that you didn’t notice an improvement in website speed with Jetpack Boost while using DIVI and WP Super Cache, it’s worth noting that performance can vary based on different configurations and environments. Jetpack Boost focuses on performance optimization primarily by providing Critical CSS, Deferring Non-Essential JavaScript, Concatenating JS/CSS and Caching.
Since you’ve tried Jetpack Boost along with other optimizations but didn’t see an improvement, it might be useful to conduct further performance testing to identify possible conflicts or bottlenecks. This could include checking for plugin conflicts, evaluating hosting performance, and analyzing server response times.
