MySpace is sharing an open source project named MySpace’s Performance Tracker which is an Internet Explorer plugin for capturing and measuring possible bottlenecks on webpages.

The plugin is a great helper to developers for:

• measure the CPU hit and memory footprint of your pages
• reviewing screenshots of the page while it renders
• reviewing rendered HTML on each point of the page’s lifecycle
• viewing estimates of the time it takes to render each section of the page in different connection speeds
• validating the content of pages against a set of proven “best practice” rules of web development.

P.S. The tool is currently in pre-alpha state.

Requirements: Windows XP+, IE6+, Adobe Flash Player 9+, Microsoft .Net framework 2.0
