Currently I am working on new App Engine application.
Unfortunately it seems that my application uses to lot of resources even for relatively small user number. So I need to determine its bottle necks and optimize them.

The Eclipse plugin for the Google App Engine provides a local App Engine environment in which you can run your program in debug or profile mode. Perhaps this could provide the information you need?
Appstats: RPC Instrumentation for Google App Engine. It is being developed by Guido himself.

EDIT: I believe AppStats will not work with Java, but there are some tips here.
