- 2. Drupal Performance Optimization Drupalis not slow Drupal is not slow The site was just not built for the context Poorly written backend Unoptimized front end Infrastructure not designed for traffic patterns
- 3. Drupal Performance Optimization Aspectsof Performance Page load time Page render time Maximum number of simultaneous users on site Maximum number of logged in users on site
- 4. Drupal Performance Optimization AuditingPerformance Document baseline performance Identify traffic patterns Evaluate website build Identify bottlenecks in the backend Identify bottlenecks in the frontend Evaluate hardware platform Identify limitations at the server level Evaluate server application configuration Identify sub-optimal configurations
- 5. Drupal Performance Optimization FactorsAffecting Performance Server configuration - hardware specs Server applications - apache, database, caching Drupal backend - how the site has been built, modules, themes, custom code Drupal frontend - internal resources, external resources, content to be loaded / rendered, complexity of HTML, JS, CSS Caching layers - varnish, CDN, browser cache
- 6. Drupal Performance Optimization ServerConfiguration Shared? VPS? Dedicated? Processor - speed? cores? dedicated? virtual? Memory - total memory available? shared? free memory? Hard disk - speed of i/o? SSD?
- 7. Drupal Performance Optimization ServerApplications Apache - threading model - MPM, Prefork, CGI, FCGI, maximum number of requests, number of children, connection time out, modules Nginx MySQL - query caching, indexes, tmp table, open tables, heap size PHP - extensions
- 8. Drupal Performance Optimization DrupalBackend Caching - page caching, views caching, caching in custom code Memcache Modules - number? unused? admin? Custom code - reviewed? SQL queries - slow queries? query log? SQL inserts - too many? logging? Disk writes - too many? Synchronous requests?
- 9. Drupal Performance Optimization DrupalFrontend Loading time Rendering time Complexity of HTML Complexity and size of CSS Complexity and size of JS Number and size of static resources Number of external resources Synchronous external resources
- 10. Drupal Performance Optimization CachingLayers Browser cache - enabled? expiry? Static caching - varnish? boost? Static resource caching - CDN? subdomains?
- 11. Drupal Performance Optimization OptimizingPerformance Quantify bottlenecks - impact? cost? time? Classify bottlenecks - critical, high, normal, low Group solutions Iterate over groups - implement and test Document results Monitor and re-evaluate
