FlyingPress is currently the most aggressive and effective performance plugin in the WordPress ecosystem. While other plugins simply cache pages, FlyingPress acts as a “delivery optimiser.” It rewrites the code structure on the fly to satisfy Core Web Vitals.

I deploy it for its superior handling of JavaScript execution. Its “Delay JS” script engine is intelligent enough to pause non-essential scripts until user interaction, ensuring that the Total Blocking Time (TBT) is near zero. Furthermore, its integrated CDN and Critical CSS generation are often more accurate than competitors. It is the tool I reach for when a site is struggling with complex DOM structures and needs to hit a 90+ mobile score immediately.
