We create our application in the best possible ways, but that may not be as efficient.
When talking about the performance of a particular web page, the first thing which strikes in our minds is
How fast does the page load when we enter the URL in the address bar and hit ‘Enter’?
Now we have an extension to monitor the speed of the page loading with Google Chrome, which also suggests us ways in which we can increase the response time of a page.This extension is called Page Speed.
You can download this extension from http://code.google.com/speed/page-speed/download.html explicitly for Chrome and for Firefox also if needed.
Before installing the extention just follow the instructions from here http://code.google.com/speed/page-speed/docs/using_chrome.html
And we are done, now we can measure the performance of our web applications at page level and get it enhanced accordingly.
