Speed Tracer (Chrome Extension)

I discovered this amazing tool a few months back created by Google called Speed Tracer. It is a Chrome Extension that allows, I suppose, just about anyone to diagnose performance issues in web applications. Take a look at the description below.


Using Speed Tracer you are able to get a better picture of where time is being spent in your application. This includes problems caused by:

• Javascript parsing and execution
• Layout
• CSS style recalculation and selector matching
• DOM Event handling
• Network resource loading
• Timer fires
• XMLHttpRequest callbacks
• Painting
• and more ...
