What happens when you type a URL and press enter
A millisecond-by-millisecond trace of what happens when you type a URL and press enter: DNS, TCP, TLS, HTTP, and the render path, timed and mapped.
Read the postTrace the milliseconds after you press enter, down to why cache beats RAM.
Web performance articles from Atyantik that start with the machine, not the metric. We trace what happens in the milliseconds after you press enter through DNS, TCP, TLS, and the render path, explain why CPU cache beats RAM down at the SRAM versus DRAM cell, and read Core Web Vitals from field data at p75 before pulling a fix. The Lighthouse post opens up its scoring model so the number stops being a mystery.
