Device Orientation Benchmark

This project is created to test the interval of Device Orientation fire for each browser tick.

Here is some of the details for the setup of the test:

  • Collect 2000 samples of event triggered
  • Calculate the highest, lowest and mean from the samples collected

Results

Below is the statistics I get after I ran the benchmark on Chrome and Firefox. Other desktop browsers seem doesn't support the Device Orientation event at the moment.

In Chrome, we can get a mean of 122ms per event call. The interval for the event call for Chrome is quite unstable where by looking at the graph generated from the data I get, I can see that it's constantly triggering the event at ~200ms and ~300ms occasionally.

On the other hand for Firefox, the mean that I got for the event triggering interval is about 53ms. The event triggering is quite consistent compare to the stats I got from Chrome.

One weird thing I find out is that both Chrome and Firefox sometimes takes a very long time for certain ticks where it can go up to more than 1000ms, I assume it's when the garbage collector kicks in and block all the thread that is running. Hope someone can explain the behavior I see here in details.
