The page you are viewing is a standard WSS v3 web part page.  Although it uses a custom site definition for branding purposes, it is based upon the out-of-the-box WSS Team Site template.  On this page are several images which are included in the master page, some custom server controls, and a few web parts (including this Content Editor Web Part, a standard Image web part displaying the Sonar Standard logo, and the BinaryWave RSSAggregator web part). 

The Sonar Standard web part below displays performance information for the current page.  At the top of the web part is summary information for the page, such as the page title, number of controls, average execution time, etc.  Clicking on the 'View Performance' button generates a performance report detailing the execution times and sizes of each linked resource (including images, scripts, style sheets, etc.) and web part on the page.  This information can be exported in XML format by clicking the 'Export Data' link.
