-Keep in mind that this test will run against your closest enabled Fly region, which may or may not be the region that your users will use. gRPC testing also works a little different, because a single HTTP/2 connection is re-used across many requests. Testing against dummy methods that don't do much is really just a test of single connection bandwidth. The best way to make sure your service is running great would be to enable the instrumentation provided in your client and service libraries and exercise your service in a real-world scenario.
