- AOL Pagetest Web Performance Tool Released as Open Source
- AOL has released an open source web performance tool called Pagetest. Pagetest is an Internet Explorer plug-in that measures and analyzes the performance of web pages. It features waterfall timing graphs, optimization checklists based on AOL's own internal standards, optimization reports, and IE integration. Pagetest offers more granular details of each HTTP request within their waterfall graphs than IBM Page Detailer or Firebug. Each HTTP request is broken down into get IP, open socket, time to first byte, and content download all color coded on each waterfall chart. See below for an example waterfall chart of CNET's news.com.
