Some ideas: There is a log_stats decorator in gaehandler.py that can be uncommented and enabled in production to give a more precise timing profile than the log coarse timing.
The main caching mechanism is in compileapp.py and the compiled code should be cached in a dict called 'cfs' which can be printed for debugging. If the caching mechanism is working, and the responses are not fast enough, then memcach'ing the responses could be used to reduce database accesses.
