        neXpert is an add-on to Fiddler which automates the classic performance best practice checks and produces a HTML report on the issues found in a Fiddler capture. neXpert adds the ability to insert step markers in Fiddler sessions to associate network objects together (create transactions). Using these steps, neXpert looks for performance issues and generates a HTML report based on the findings. A TCP model provided by Microsoft Research as well as a rudimentary algorithm to mimic web browser is used to generate response time predictions (Still considered Beta). More information can be found at the neXpert blog:
