If you mean to run this benchmark across different browsers, you should know there might be some problems with the time measurement technique you’re using. Read http://calendar.perfplanet.com/2010/bulletproof-javascript-benchmarks/ http://calendar.perfplanet.com/2010/bulletproof-javascript-b... for a detailed explanation. Why not use Benchmark.js https://github.com/mathiasbynens/benchmark.js https://github.com/mathiasbynens/benchmark.js for your test case? This library will take care of all the issues mentioned in the article I linked to. Or just take the easy road and use http://jsperf.com/ http://jsperf.com/ which uses Benchmark.js behind the scenes :)
