Tuning Click-Once deployment performance with VRTA and PowerShell

Some of our client applications get distributed using the Click-Once paradigm. One day we noticed that the time between the initial click on the download link in the browser and the complete initialization of the Click-Once desktop client application took much longer than a user would tolerate. We decided to debug the deployment of the application and fix the problem. We chose the Microsoft Netmon 3.2 and the VRTA (Visual Round Trip Analyzer) for the initial analysis.
