第一个是Pingdom Tools - Full page test 这个能详细测试网页各部分打开的时间

官方介绍:

The Full Page Test loads a complete HTML page including all objects (images, CSS, .s, RSS, Flash and frames/iframes). It mimics the way a page is loaded in a web browser.

The load time of all objects is shown visually with time bars.

You can view the list of objects either in load order or as a hierarchy. The hierarchy view allows you to see which objects are linked to in for example a CSS file.

Every test also shows general statistics about the loaded page such as the total number of objects, total load time, and size including all objects.
