CDN & Edge

A CDN puts your content closer to visitors. Sounds simple. The implementation details make the difference between marginal improvement and dramatically faster sites.
This category covers Cloudflare, Bunny CDN, KeyCDN, and other content delivery networks. You’ll find setup guides, optimization tips, configuration mistakes to avoid, and comparisons based on real performance testing. I also cover edge caching, which goes beyond traditional CDN to cache dynamic content at the network edge.
Most CDN tutorials stop at “enable it and you’re done.” That gets you maybe 30% of the potential benefit. Proper cache rules, origin optimization, and edge computing configuration unlock the rest. These guides cover the advanced setup that actually makes your site fast globally, not just in one region.
