Question How fast is your browser?

[Magic Carpet]

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. Some call DOM APIs directly from ECMAScript 5 (ES5), ECMASCript 2015 (ES6), ES6 transpiled to ES5, and Elm transpiled to ES5. Others use one of eleven popular JavaScript frameworks: React, React with Redux, Ember.js, Backbone.js, AngularJS, (new) Angular, Vue.js, jQuery, Preact, Inferno, and Flight. Many of these frameworks are used on the most popular websites in the world, such as Facebook and Twitter. 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.

Images aren't necessary, but please state your cpu speed. The web browser of your choice. Mine is Edge 83. Thank you.

The easiest way to solve this problem is to hash the resource being cached and compare the hash value to that of another resource with same name and different URL and if it matches, just point to the original resource instead of storing duplicates. I don't know how privacy would be compromised by storing most reused web components in this manner.

If I want to tell whether you've visited Anandtech, I can use a resource that only Anandtech loads (like the logo) and have my page load it. Based on whether that load takes a noticeable amount of time or not I tell whether that resource is cached, and by that know that you've visited the page.

There's a reason why the VERY OBVIOUS method of reference counting is something all browsers have moved away from, and it isn't because you're smarter than everyone writing browsers.
