Behind the Optimization A Deep Dive Into WordPress Performance Tuning.pdf

Key Optimization Strategies

1. Hosting Environment:
- Choose the Right Host: Opt for managed WordPress hosting or consider dedicated/VPS servers for high traffic.
- Use CDNs: Reduce latency with Cloudflare or Amazon CloudFront.

2. Caching Mechanisms:
- Page Caching: Use W3 Total Cache or WP Super Cache to serve static HTML.
- Object Caching: Implement Memcached or Redis for database query caching.

3. Image Optimization:
- Compress Images: Tools like TinyPNG or Smush.
- Serve Scaled Images: Use `srcset` and responsive images.

4. Minification and Concatenation:
- Minify CSS/JS: Use Autoptimize or Fast Velocity Minify.
- Concatenate Files: Reduce HTTP requests by combining CSS and JS files.

5. Database Optimization:
- Clean Up Database: Remove revisions, spam comments with WP-Optimize or Advanced Database Cleaner.
- Optimize Tables: Use phpMyAdmin or WP-DBManager.

6. Update and Monitor:
- Keep Updated: Regular updates for core, themes, and plugins.
- Monitor Performance: Tools like Google PageSpeed Insights, GTmetrix, or Pingdom.

Advanced Techniques

1. GZIP Compression:
- Enable GZIP: Compress files for faster transfer via .htaccess or hosting control panel.

2. Browser Caching:
- Set Expiry Dates: Cache files for faster loading on return visits.

3. PHP and HTTP/2:
- Use Latest PHP Version: PHP 7.x offers better performance.
- Enable HTTP/2: Faster protocol supported by modern browsers and servers.

4. Database Indexing:
- Create Indexes: Improves database query speed with careful planning.

5. Asynchronous and Deferred Loading:
- Load JavaScript Asynchronously: Use `async` or `defer` attributes to ensure non-blocking rendering.

Monitoring Tools

- Google PageSpeed Insights: Provides performance insights and recommendations.
- GTmetrix: Detailed page speed reports.
- Pingdom: Monitors uptime and performance globally.

Key Metrics
- Page Load Time: Aim for under 2 seconds.
- Time to First Byte (TTFB): Should be under 200ms.
- Total Page Size: Ideally under 2MB.
- Number of Requests: Reduce HTTP requests for faster loading.
