How it works

Every request of a real page load is a note. The resource type picks the instrument, the weight sets the volume, third-party services like ads and analytics play out of tune, and while the main thread is busy the orchestra falls silent.

The beat sets the tempo and the chords, and the page load plays on top as the melody.

Dashed notes are third-party services: ads, analytics, widgets. They play a quarter tone out of tune.

Red at the bottom is a busy main thread. While the browser thinks, the orchestra falls silent.
