Hi Gary, Practically speaking, for an app that hasn't been given elevated permissions, you should be able to have at least 30 concurrent requests - equating to around 400 QPS if your app is fairly efficient. What problems are you running into that lead you to conclude you're hitting a limit at 4 QPS, and that the problem is at App Engine's end?
