Test methodology
What does the DOM Create Source Test measure?
It measures how efficiently the browser creates, inserts, updates, removes, and rebuilds DOM elements.
What workload does the DOM Create Source Test run?
Seven phases are repeated three times. They cover createElement(), appendChild(), DocumentFragment, template cloning, insertAdjacentHTML(), attributes and classes, remove-and-recreate cycles, and five-level nested trees.
How is DOM Create Source different from DOM Search?
DOM Search measures finding and traversing existing nodes. DOM Create Source measures constructing and modifying them.
How is the DOM Create Source score calculated?
Completed creation and mutation operations are divided by elapsed time and multiplied by the official weight. Higher scores are better.
How to interpret the result
The result reflects how efficiently the browser creates, inserts, updates, removes, and rebuilds DOM elements.
