The development datastore is always much much much faster as the "real" datastore. Most likely you are runninng into issues like: http://stackoverflow.com/questions/7049717/appengines-entity-group-write-limit-is-very-limiting-in-real-life-application Check out "usage notes" at: http://code.google.com/appengine/docs/java/datastore/hr/overview.html A "cool" thing would be to artificially throttle the development datastore to notice such problems early on and not when deploying the app. Maybe that's a feature request...
