Question 1

What are the desktop Core Web Vitals for github.com?

Accepted Answer

github.com desktop-only p75 metrics from Google CrUX: LCP 1784ms (good), INP 62ms (good), CLS 0.060 (good). Desktop typically shows better LCP + INP than mobile due to faster hardware + network.

Question 2

Why is desktop performance better than mobile for github.com?

Accepted Answer

Desktop hardware (more CPU, more RAM, wired network) typically renders pages faster than mobile (battery-constrained CPU, slower cellular). Most sites show 30-60% faster LCP + 40-70% lower INP on desktop. CLS varies less by device. Compare directly at /github.com/mobile for the same time window.
