Javascript performance across many browsers – run your tests and share the results here


jsperf is like a horserace – it allows you to set up and run your own test cases simultaneously on multiple remote browsers to see the performance differences. One recent one I was checking out was “Math.floor(4.6)” versus “~~4.6”. This is a powerful tool to diagnose some cross browser performance issues, and to have a look at what other people have been benchmarking.
