I am using Yslow recommendations, to improve UI/page performance. Are there any tools to benchmark and test that? I want to take the initial benchmark of the page, the processing time, rendering time, or each file. Then, after applying each of the rule, I need to take benchmark and check the details.
TIA.
You can probably try using the Web Timings API on W3C with Selenium 2. You can search google for the exact usage steps.
Another resource I have found extremely useful in past has been the following post on IBM’s website especially the section called Measuring Performance
