Abstract: Systems, methods, and computer-readable and executable instructions are provided for generating a stateful simulation program. Generating a stateful simulation program can include arranging a number of recorded request-response pairs in a sequence order to generate a number of tracks. Generating a stateful simulation program can also include assigning a state to each of the number of request-response pairs and calculating a cost for each state based on a number of current requests. Furthermore, generating a stateful simulation program can include generating the stateful simulation program based on a selected state with a desired cost.

Abstract: A method for generating a performance simulation of a real service can include scheduling a time for a number of responses to be sent based on a number of response time metrics and determining a delay for the number of responses based on a number of data throughput metrics. The number of responses can then be sent based on the time and the delay.
