How many times did you run your tests? Did you deploy to production or use
the development server for your tests? If you used the dev server, what are
the specs of the machine you used to run the tests?

There are a lot of confounding variables when running these kinds of
performance measurements. The best way would be to deploy your app to
production App Engine and hammer away with a load testing app such as
ApacheBench: http://en.wikipedia.org/wiki/ApacheBench
