Running in browser

Chrome/Chromimum

For best results run your browser with following options:

--enable-benchmarking --js-flags "--expose_gc --flush_code --gc_global"

Details:

• --enable-benchmarking exposes window.chrome.Interval which

gives us at least microseconds precision (instead of milliseconds that Date can provide)

• --js-flags passes options to the V8: --expose_gc adds window.gc

which forces the garbage collector to do it's work; --flush_code makes the GC collect (hopefuly) all of precompiled code; --gc_global makes the GC even more aggresive.

Running from CLI

Node.js

Node.js uses V8 engine, so the options are similar to the one we used for Chrome. Except for the timer thing which is a Chromium extension to DOM. Instead we'll use microtime module <https://github.com/wadey/node-microtime>:

$ npm install microtime

All other options are set in bench_config.json.
