Project Overview
A restaurant owner contacted me because their WordPress website was loading slowly, especially on pages with large image galleries showcasing menu items and restaurant interiors.
Slow loading times were affecting visitor engagement and making it difficult for customers to browse the menu or find contact information quickly.
The objective of the project was to significantly improve page speed while preserving the visual quality of the restaurant’s image-heavy content.
Initial Performance Audit
A full performance audit revealed several common issues affecting the website’s speed.
These included:
• numerous unoptimized high-resolution images
• unnecessary plugins loading additional scripts
• no caching system configured
• lack of a CDN for faster global asset delivery
• oversized images exceeding container dimensions
These issues caused the website to load slowly and created unnecessary server load.
Media Optimization
Because restaurant websites rely heavily on photography, image optimization was the most important step.
The media library was reviewed and optimized by:
• resizing images to appropriate container sizes
• compressing images without noticeable quality loss
• removing duplicated or unused media files
This process reduced the media library size by approximately 350 MB, significantly improving page weight.
Plugin and Asset Cleanup
Several plugins were either unused or duplicated functionality.
After reviewing the plugin list, unnecessary plugins were removed and scripts were reduced.
In total, nine plugins were removed, which improved stability and reduced server processing overhead.
Caching and CDN Implementation
Since the website was hosted on a LiteSpeed server, caching was implemented using LiteSpeed Cache.
The caching setup included:
• page caching
• CSS and JavaScript optimization
• lazy loading for images
• cache preloading
Additionally, Cloudflare CDN was integrated to ensure faster delivery of static assets for visitors in different locations.
Performance Results
After completing the optimization workflow, the website’s loading speed improved dramatically.
Average page load time was reduced to approximately 1.9 seconds, providing a much faster browsing experience.
Google PageSpeed scores also improved significantly, reaching 94.
Quality Assurance
After implementing the optimizations, a full review of the website was performed to ensure:
• layouts remained visually consistent
• images displayed correctly
• caching settings did not interfere with functionality
Multiple pages were tested across different devices to confirm stable performance.
Results
The performance optimization significantly improved the website’s speed and stability.
Key outcomes included:
• page load time reduced to around 2 seconds
• nine unnecessary plugins removed
• 350 MB reduction in media storage
• PageSpeed score improved to 94
Long-Term Impact
The website now loads quickly and provides a smoother experience for visitors browsing menus, viewing photos, or contacting the restaurant.
With optimized media assets and proper caching infrastructure in place, the site is easier to maintain and better prepared for future growth.
