Web Tracing Framework Extension

The Web Tracing Framework is a collection of libraries, tools, and scripts aimed at web developers trying to write large, performance-sensitive Javascript applications. It's designed to be used in conjunction with the built-in development tools of browsers but goes far beyond what they usually support at the cost of some user setup time.

This is a Chrome extension that makes it easy to use the Web Tracing Framework on your pages and gathers additional information from Chrome such as garbage collection events. It is designed to be used in conjunction with user instrumentation.

For more information on the Web Tracing Framework and how to get started, see: http://google.github.io/tracing-framework

NOTE: until Chrome bug 158234 is fixed the timing information on Chrome/Windows is incorrect. See more known issues at https://github.com/google/tracing-framework/blob/master/KNOWN_ISSUES.md
