List of web browser performance tests

List of web browser performance tests is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of web browser performance tests rather than just read about it. In short: There are a variety of software performance tests for web browsers, which measure rendering and animation, DOM transformations, string operations, mathematical calculations, sorting algorithms, graphic performance tests and memory instructions. Browser speed tests have been used during browser wars to prove superiority of specific web browsers.

Key takeaways

List of web browser performance tests belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect List of web browser performance tests to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of List of web browser performance tests from memory before moving on to harder problems.

Reference excerpt

There are a variety of software performance tests for web browsers, which measure rendering and animation, DOM transformations, string operations, mathematical calculations, sorting algorithms, graphic performance tests and memory instructions. Browser speed tests have been used during browser wars to prove superiority of specific web browsers.

List

Speedometer Speedometer was originally developed by the WebKit team at Apple and released in 2014 and was updated in 2018. Speedometer 3.1 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. 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.

Peacekeeper Peacekeeper is a platform-independent benchmark by Futuremark that tests rendering, mathematical and memory operations. It takes approx. 5 minutes for execution and tells the results of other browsers with different CPUs. Futuremark stopped maintaining Peacekeeper in July 2015. The test was taken offline in March 2018 and is no longer available.

Testdrive Microsoft maintains a suite of performance-oriented tests, often designed to test and stress JavaScript and rendering performance. These tests are typically designed to highlight IE's performance, but are compatible with other major browsers.

WebXPRT WebXPRT is a cross-platform browser benchmark that runs HTML5- and JavaScript-based workloads. The benchmark provides scores for six individual workloads, as well as an overall score. WebXPRT is published by the BenchmarkXPRT Development Community, which is administered by Principled Technologies, and is one of the BenchmarkXPRT benchmarks. WebXPRT 4 is the most current version of WebXPRT.

Wirple BMark Performance test for HTML5 3D applications. It tests performance in both Canvas3D and WebGL.

Dromaeo (superseded by Kraken) A Mozilla test suite based on SunSpider tests. It takes several minutes for execution and displays very detailed information about every single test task.

Kraken (active) Another JavaScript test suite from Mozilla, released September 14, 2010.

JetStream (active) A JavaScript test suite developed by Apple.

SunSpider (superseded) SunSpider is a benchmark created by the webkit team that aims to measure JavaScript performance on tasks relevant to the current and near future use of JavaScript in the real world, such as encryption and text manipulation. The suite further attempts to be balanced and statistically sound. Version 0.9 was released by the WebKit team in December 2007. It was well-received, and other browser developers also use it to compare the JavaScript performance of different browsers. Version 0.9.1 was released in April 2010. Version 1.0 was released in April 2013.

V8 (superseded) A JavaScript test suite by Google, used to optimize the Google Chrome web browser. It does not test rendering performance. It was superseded by Google's Octane benchmark.

Octane (unmaintained) Google's JavaScript test suite which replaces the V8 benchmark. According to Google, "Octane v.1 consists of 13 tests, 5 new ones and 8 from the original V8 Benchmark Suite." Octane v.2 supplanted v.1, consisting of "17 tests, four more than Octane v1." As of April 12 2017, Google no longer maintains Octane.

GUIMark 2 This tests vector, bitmap, and text rendering for both Adobe Flash and HTML5.

MotionMark 1.3 (active) A graphics benchmark developed by Apple.

Worked examples

Example 1 — a first encounter with List of web browser performance tests

Start with the simplest possible case. Write down what List of web browser performance tests claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of web browser performance tests before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of web browser performance tests ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of web browser performance tests

In research: List of web browser performance tests appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of web browser performance tests in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of web browser performance tests is common in secondary-school and first-year university syllabi. It links to neighbouring topics Benchmarks (computing), Computer performance, Computing comparisons, so understanding it makes those chapters shorter.
In everyday life: Look for List of web browser performance tests outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
