In December i was writing about Google’s speed tracker. Today, i had to test some web page performance, so, i tried googles speed tracker – and the results was not so informative as i wished to be. I had to get more data on what is slowing down the page.

So I went on a hunt for the best web page performance tool, wich would give me the information i needed to improve speed of web page.

After some hours of searching, i found the tool i was looking for – http://www.webpagetest.org, and ofcourse i share it with you. With this tool i could easily spot problems wich were slowing down the web page. Thats all i need :)

Here are some images, just to see what are the results…

Google launched new extension for Google chrome called Speed Tracer.

Speed Tracer is a tool to help you identify and fix performance problems in your web applications. It visualizes metrics that are taken from low level instrumentation points inside of the browser and analyzes them as your application runs. Speed Tracer is available as a Chrome extension and works on all platforms where extensions are currently supported (Windows and Linux).

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.
