web-tooling-benchmark's Introduction

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/.

Building

This was tested with Node 6, Node 7 and Node 8.

To build the benchmark suite, run

$ npm 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.

Running

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

$ node dist/cli.js
Running Web Tooling Benchmark 0.3.1...
--------------------------------------
         acorn:  9.19 runs/sec
         babel:  6.74 runs/sec
       babylon:  8.72 runs/sec
         buble:  7.67 runs/sec
          chai: 13.28 runs/sec
  coffeescript:  6.80 runs/sec
        espree:  5.45 runs/sec
       esprima:  7.67 runs/sec
        jshint:  8.41 runs/sec
         lebab:  8.88 runs/sec
       prepack:  8.81 runs/sec
      prettier: 11.21 runs/sec
    source-map: 17.22 runs/sec
    typescript: 10.70 runs/sec
     uglify-es: 20.16 runs/sec
     uglify-js:  8.22 runs/sec
--------------------------------------
Geometric mean:  9.37 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 (d8, jsc, ch or jsshell) to run the special bundle in dist/cli.js.
