到目前为止各个测试只着重于JavaScript 的运行效率, 都避开图片渲染, 文字渲染, 网页其他元素.
Mootools test以目前最完整的模拟测试浏览器的真实效率.
Notes about testing:
- All of these tests were performed on the same Windows XP SP3 machine that is wired into a network to eliminate the effects of wireless disturbances.
- All browsers started with a clean profile and no add-ons/extensions were installed.
- All browser data, including caches, were cleared before each test was run.
- Only one browser was open at a time, and no other applications (other than standard XP services) were running.
- Internet Explorer 8 was used in the native rendering mode (”standards compliant mode”).
- No plug-ins (Flash, Java, etc…) were installed on the machine to ensure that slow performance wasn’t due to the loading of a plug-in.
