I have some code tweaks that I believe will improve the performance of my pages. However, I'm not sure how to use the tools I have to get a total response time of my page (before and then after my code change to compare).
I have Firebug, Developer dashboard and Fiddler 2 installed. As far as I can see, they only show response times for each HTTP request. How would I get the total response time of the page I'm testing in either of these tools?
