Apple has released the second iteration of Speedometer, which is a tool designed to test the web app responsiveness. Apple launched Speedometer in 2014, and this new version comes with a handful of changes on board to help the developers test their browser engines.
Speedometer 2.0 is capable of running 480 tasks in a browser window using a combination of multiple technologies. The idea is to determine how long each of these tests take, and offer a detailed report to the user. This updated version of Speedometer has come at the right time as browser technologies have evolved dramatically since 2o14. Speedometer 2.0 also changes the way some of these tests are calculated.
