Networking & HTTP·Networking from DNS to production

Performance and CDNs

Reduce latency with caching, compression, HTTP/2 and edge delivery.

Beginner 14 min read Lesson 9 of 300 Challenge included

What you will be able to do

Enable Brotli or gzip.
Cache static assets at the edge.
Use HTTP/2 or HTTP/3.
Measure p75 and p95, not only the average.

In plain English

Performance is round trips, payload size and server time. Compression reduces bytes, caching avoids requests, HTTP/2 multiplexes and a CDN serves from a nearby edge. Measure with real timings; do not guess.
