Ultimate Guide to CDN Performance Tuning

Performance is the lifeblood of any modern web application. A slow website leads to lost customers and lower search rankings. In this guide, we'll explore advanced techniques to optimize your CDN Engine deployment.

1. Optimize Cache Headers

The most common mistake we see is improper Cache-Control headers. Ensure you are setting long max-age values for static assets like images and CSS.

location ~* \.(jpg|jpeg|png|gif|ico|css|js)$ {
    expires 365d;
    add_header Cache-Control "public, no-transform";
}

2. Enable Compression

Brotli and Gzip compression can significantly reduce the size of your text-based assets. CDN Engine supports both out of the box, but you need to ensure your origin server is configured correctly or let the edge handle it.
