In a new task of reducing web page load time of a website, I was extremely using Yslow and Firebug to conduct the initial study on performance and page load test. All you need to is a Firefox browser with Yslow and Firebug add-ons installed and you would be able to gather and finally understand the bottle necks of your web page performance.
- Total page size with cache and without cache
- Total page load time with cache and without cache
- load time of each content of web page
- Total number of requests made to server to load complete web page.
Once you are done with the above study, YSlow also provides suggestions on ‘best practices for speeding up a web site‘. Yahoo exceptional Performance team has identified a number of best practices for making web pages fast. The list includes 35 best practices divided into 7 categories. Follow the link provided above, they are really helpful for web designers.
