In general the testing software is available online, located on a website, where different algorithms are loaded and performed in the browser client.
Speedometer was originally developed by the WebKit team at Apple and released in 2014 and was updated in 2018.
[1] Speedometer 2.0 tests a browser's Web app responsiveness by timing simulated user interactions.
This benchmark simulates user actions for adding, completing, and removing to-do items using multiple examples in TodoMVC.
Each example in TodoMVC implements the same todo application using DOM APIs in different ways.
The performance of these types of operations depends on the speed of the DOM APIs, the JavaScript engine, CSS style resolution, layout, and other technologies.
Peacekeeper is a platform-independent benchmark by Futuremark that tests rendering, mathematical and memory operations.
These tests are typically designed to highlight IE's performance[citation needed], but are compatible with other major browsers.
It takes several minutes for execution and displays very detailed information about every single test task.
