Key Takeaways
From the server to the browser, all the layers that make a website faster. HTTP/3, CDN and Edge Computing.
End-to-End Acceleration
A fast site is not just about image compression. A layered optimization is required at the infrastructure level.
Network Layer
- HTTP/3 (QUIC): UDP-based, faster connection establishment and better performance in packet loss.
- CDN (Content Delivery Network): Deliver the content from the edge server closest to the user. You can use Cloudflare, Fastly or AWS CloudFront.
- Brotli Compression: Text compression technology that is 15-25% more efficient than Gzip.
Server Tier
- Redis/Memcached: Reduce response times by caching database query results.
- OPcache: PHP Reduce script compilation time to zero by caching the byte-code.
- Database Indexing: Add indexes to frequently queried columns.
Browser Layer
With Service Worker, you can establish offline experience and pre-loading strategies. Set long-term cache rules for static files with Cache-Control headers.
