Google has announced a new component that’s been added to the new Analytics, the Site Speed report.
The Site Speed report tracks the loading time for each page of your site as various visitors access it. Loading time tracking needs to be enabled before Google will start to collect the numbers, but this will prove very useful to those trying to identify and solve performance problems with their site or server.
Google has prepared a custom report that takes advantage of Site Speed statistics. If you click on this link, that report will be set up for the currently active site in your Analytics account.
