The Challenge

Several of the websites were suffering from slow load times, which adversely affected user satisfaction and conversion rates. The common issues identified included unoptimized HTML, CSS, and JavaScript files, large images, and inefficient caching mechanisms.

Solution: LiteSpeed Cache

Step 1: Installation and Configuration

• Tool Used: LiteSpeed Cache Plugin
• Action: Installing and configuring the LiteSpeed Cache plugin on each website was the first step. Ensured that the server was running LiteSpeed for optimal compatibility and performance.

Step 2: HTML, CSS, and JavaScript Minification

• Action: Enabled the minification and combination of HTML, CSS, and JavaScript files. This reduced the size of these files and the number of HTTP requests, leading to faster load times.
• Outcome: Significant reduction in page size and improved load times.

Step 3: Image Optimization and Lazy Loading

• Action: Activated image optimization features in LiteSpeed Cache to automatically compress images without losing quality. Implemented lazy loading to defer the loading of offscreen images, improving initial load times.
• Outcome: Reduced overall page weight and faster rendering of visible content.

Step 4: Cache Management

• Action: Configured browser caching and server-side caching to store static resources and reduce the need for repeated downloads. Regularly purge the cache to ensure users receive the most updated content.
• Outcome: Faster subsequent page loads for returning visitors and improved server response times.

Step 5: Advanced Settings and Tweaks

• Action: Utilized LiteSpeed Cache’s advanced settings, such as HTTP/2 push, ESI (Edge Side Includes), and database optimization. Tailored settings to the specific needs of each website.
• Outcome: Enhanced performance, especially for dynamic content and database-driven sites.
