Case Study: Server-Side Optimization Overhaul
A high-traffic WordPress site struggled with unpredictable slowdowns, high CPU usage, and constant warnings from their hosting provider. The frontend was relatively optimized, but the backend server stack was the bottleneck.
The Challenge
The server was running default Apache/PHP settings with no advanced caching layers. Traffic spikes would send response times over 10 seconds, and Time to First Byte (TTFB) was often 2–3 seconds even on cached pages. Database queries piled up and resource limits were frequently hit.
The Fix
I migrated the site to a tuned Nginx + PHP-FPM setup, configured Redis object caching, and enabled full-page caching with optimized rules for dynamic content. MySQL was tuned with query caching, proper indexing, and connection pooling. Brotli compression and HTTP/2 were enabled at the server level, and a global CDN (Cloudflare) was added for static assets.
The Outcome
- TTFB reduced from 2–3s to under 500ms consistently.
- Server CPU usage dropped by 60% under load.
- Handled 3x traffic spikes without downtime.
- Hosting costs were reduced by consolidating resources and improving efficiency.
