Google has recently added a new tool to their Google Web Toolkit called Speed Tracer. Speed Tracer is a tool to help you identify and fix performance problems in your web applications. It is available as a chrome extension and is useful for the application developers to identify problems in slow-to-respond applications.Speed tracer uses a sluggishness graph (generated after continuous monitoring of your applications) in combination with many other metrics. It visualizes metrics that are taken from low level instrumentation points inside of the browser and analyzes them as your application runs.
How It Works ?
After the graph is generated you only need to look at the Y axis of the graph to evaluate the performance
- If the y-axis is close to zero, then the app is fast
- If the y-axis registers around 100%, then the app is, well, sluggish
I think that this extension will add a sophisticated approach to the way in which the application developers work. Moreover i expect a great rise in the number of similar applications in near future. You can check out the download instructions from the link below.
