| Test: | |
| Use cloudi_service_request_rate to send service requests to the | |
| http_req integration test written in a supported programming language. | |
| Vary the number of sending service processes and the number of | |
| receiving service processes (either threads or OS processes when testing | |
| external services) to determine the effect on the maximum stable request | |
| rate that can be sustained (for more than 20 seconds with the expectation | |
| of maintaining the request rate indefinitely, i.e., the request rate that | |
| can be sustained without having any errors). The destination refresh | |
| method (a service configuration parameter, either immediate_closest or | |
| lazy_closest) and the duo_mode (a service configuration option) are both | |
| settings for the sender (cloudi_service_request_rate). | |
