Response time: The amount of time it takes for the Interact runtime server to respond to an API request as measured from the client side.

Throughput: The number of transactions per second.

Transaction: A call to the Interact runtime server by the Interact API, including calls defined by the InteractAPI class such as startSession and setAudience. The executeBatch call is one transaction, even though it can contain several commands. These do not include methods that work with response objects, for example, the Offer class.
