Could you give a little more detail on how this works. The cedexis website mentions tags that need to be placed on a website. I'm assuming javascript recording the time it takes to load resources. Is this correct? Is there more to it?
Please go to http://www.lemonde.fr/ -- do a view-source, search for "radar", and you will see our javascript. You can also use firebug to get a sense of what's going on.
Please send me an email if you need more info: prakash@cedexis.com
