Web Tooling Benchmark

This is a benchmark suite designed to measure the JavaScript related workloads commonly used by Web Developers nowadays, for example the core workloads in popular tools like Babel or TypeScript. It's the explicit goal to measure only the JavaScript performance aspect, which is affected by the JavaScript engine, and not measure I/O or other unrelated aspects.

See the in-depth analysis for a detailed description of the tests included in this benchmark suite.

The latest browser version of the benchmark is available at https://v8.github.io/web-tooling-benchmark/.

Support

To see the supported Node.js versions of the current version of the Web Tooling Benchmark, see the node_js section of our CI configuration.

Building

To build the benchmark suite, run

m install

assuming that you have a working Node.js installation. Once the command is done, it produces a bundled version that is suitable to run in JS shells (i.e. d8, jsc or jsshell) in dist/cli.js and another bundle in dist/browser.js that is used by the browser version in dist/index.html.

To build an individual benchmark rather than the entire suite, pass the --env.only CLI flag:

m run build -- --env.only babel

Running

You can either run the benchmark suite directly via Node, i.e. like this:

de dist/cli.js
ing Web Tooling Benchmark 0.3.2...
----------------------------------
     acorn:  6.06 runs/sec
     babel:  6.23 runs/sec
   babylon:  6.73 runs/sec
     buble:  5.19 runs/sec
      chai:  9.60 runs/sec
ffeescript:  4.68 runs/sec
    espree:  2.65 runs/sec
   esprima:  5.92 runs/sec
    jshint:  6.12 runs/sec
     lebab:  6.72 runs/sec
   postcss:  5.01 runs/sec
   prepack:  4.54 runs/sec
  prettier:  3.54 runs/sec
source-map:  6.58 runs/sec
typescript:  7.83 runs/sec
 uglify-es: 13.54 runs/sec
 uglify-js:  3.70 runs/sec
----------------------------------
etric mean:  5.74 runs/sec

Or you open a web browser and point it to dist/index.html, or you can use one of the engine JS shells to run the special bundle in dist/cli.js. The easiest way to install recent versions of the supported JS engine shells is to run jsvu. Afterwards, you can run the benchmark as follows:

akra dist/cli.js
vascriptcore dist/cli.js
idermonkey dist/cli.js
 dist/cli.js

To run an individual benchmark rather than the entire suite via Node, pass the --only CLI flag:

m run build -- --env.only babel && npm run benchmark
