Optimizing High-Traffic Drupal Sites with Caching, CDN, and Redis

Guide to Boosting Performance on Drupal High-Traffic Sites

Andrea Corda’s technical guide offers a thorough overview of performance strategies for high-traffic Drupal sites. It covers essential areas: caching, frontend optimization, backend tuning, infrastructure, performance modules, and real-time monitoring. The article is well-structured, blending developer-level insights with actionable advice for site architects and decision-makers.

Highlights include using Varnish for HTML caching, BigPipe for authenticated users, and Redis for backend caching. Frontend tips focus on lazy loading, critical CSS, and WebP, while infrastructure advice recommends scalable setups with Kubernetes, load balancers, and CDN integration. The blog also emphasises performance testing (e.g., JMeter, Lighthouse) and highlights the connection between speed and SEO, as well as stability under load.

Though framed as a promotional piece for GeoNovation services, the technical depth and module-specific recommendations make it a valuable reference for performance-focused Drupal teams.
