Measuring the Business Value of AJAX

ASP.NET AJAX is well known for its ability to improve the user experience of Web applications. With Visual Studio Team System you can also measure the business value of adding ASP.NET AJAX to your Web applications. Specifically you can use the Load and Web Testing capabilities of Visual Studio Team System to explore how the difference in HTTP data transmission size affects the performance and scalability characteristics of the Web application.

In the past I am sure I managed to get fiddler to work on my local machine by edit the registry settings relating to the local loopback.

I am also not convinced on the accuracy of your testing. From the fiddler trace you had it looked like the .png images came down with the original post (non-ajax pages) and cached at that point. The diffence in the page size of the AJAX vs NON-AJAX pages would have been down to the difference in the size of the markup of the two pages. I.e. the full markup for the NON-AJAX page and the partial page markup for the AJAX page. From the example it isn't immedialtely clear whether the images are being posted each time for the NON-AJAX part of the load test.
