The tests were performed on Heroku private-l dyno running in Virginia, United States, Heroku region against a DynamoDb table in us-east-1 AWS region. The DynamoDb table had 10_000 RCU/WCU provisioned read/write capacity. For each request body "shape", the test was performed 1000 times. Rate of requests was limited at 2 per second to avoid server-side request throttling. The test measured time to execute HTTPS POST request, i.e. time to construct payload body is not part of the reported average execution time.
