Apple’s WebKit team announced Speedometer 2.0 on Monday. This is a benchmarking suite designed to allow browser engineers to test their browser engines, and it’s part of Apple’s contribution to the broader WebKit community.
Speedometer 2.0 runs a series of tasks—480 of them—in a browser window using a host of web and browser technologies. The software measures how long each of these tests takes, and provides a detailed report. You could run this test in your own browser (that’s my iMac’s Safari score below), but it’s designed to let engineers get a handle on how well their engines perform.
