Using Yslow To Increase Web Page Speed
Yslow is an addon you can add to a browser like Firefox or Chrome so that you can analyze web pages. With the analysis, you can determine some areas that require upgrading.
When Firebug and Yslow addons are installed in Firefox, you simply open Firebug and select the Yslow Tab.
To run a Yslow check,
1) Open the desired web page.
2) Select ‘Run test’
After a test is completed, you can see your score and a list of grades.
