Latency numbers every frontend developer should know

This post provides a frontend developer's perspective on latency numbers, drawing inspiration from Jeff Dean's work. It details various latency estimates for different network conditions (Wifi, 5G, LTE, 3G), server distances (same cloud region, same continent, other side of Earth), and processing times (frame budget, JS/HTML/CSS parsing). It also discusses human perception of time related to responsiveness and sluggishness, and mentions React Server Components as a technology to move network waterfalls to the server for improved performance.
