It can be explained by the fact that Opera isn't the main rivals of Firefox in the browser market. Edit: http://arewefastyet.com/faq.html http://arewefastyet.com/faq.html The team's explanation: Right now, the performance tests are run on a Mac, which means no IE. Also the tests rely on a "shell" JS engine that runs in a command line. It doesn't test browsers. We'll change that, eventually.
