AppWrench Thinks My Code Needs Help

One of my fellow Appirians sent me an email today pointing me to the AppWrench site. AppWrench is a profiling tool for App Engine that runs both locally (for free!)and for applications deployed on App Engine. In addition to profiling, you can also display Data Store and Memcache API calls as well as log files.

The one thing that caught his attention is that the screenshots on the site reference my code! Apparently my code is so crappy that it needs profiling to improve it.

Perhaps I should buy my own book, Beginning Jave Google App Engine, so that I can learn something.
