• Server and hosting adjustments: configuration of cache, CDN, and server stack
• Frontend optimization: JavaScript and CSS minification, lazy loading implementation, file compression, and similar improvements
• Backend optimization: database and query tuning, removing unnecessary third-party extensions, and other performance enhancements
• Monitoring and reporting: performance tracking after updates, followed by a clear summary of all implemented improvements
