Hi Alex, It's impossible to give a useful comment without first seeing the code that you're using. Speaking from my own experience, I have a personal site that serves reasonably datastore-intensive pages, and typically total CPU milliseconds doesn't exceed about 600 - that's to do several get requests and at least one query. So it's certainly possible to do useful work with the datastore and come in well below the 1300 to 1400ms you quote.
