Optimize AWS Ubuntu Web Server

My production web server runs on AWS with Ubuntu 20.04 and, at the moment, page loads—especially on the product pages—are painfully slow. The issue is not initial server response; it is the actual content load time once the request is in motion.

What I need is a focused investigation into whatever is throttling throughput, followed by concrete optimisations that leave the site obviously faster when those product pages are requested.

Typical tasks will include inspecting the current web-server stack (Apache or Nginx, PHP-FPM, Node—whatever you discover is in play), checking resource usage through CloudWatch and top/htop, tightening configs, introducing or tuning caching layers, and, if warranted, suggesting a lightweight CDN or image optimisation tweak. Feel free to spin up test instances or use staging if that keeps my live traffic safe.

Deliverables
• Diagnosis report that pinpoints the bottlenecks (CPU, I/O, network, code, query, etc.).
• Adjusted configuration files and any scripts or commands you apply.
• A brief summary showing before-and-after metrics (page-load waterfalls, Lighthouse scores, or similar).
• Clear rollback instructions in case I ever need to undo a change.

Acceptance criteria: product pages should show a measurable reduction in content load time (ideally by at least 50 %) without breaking existing functionality.

If you have deep AWS, Ubuntu 20.04, and web-performance expertise, let’s get this server moving.
