Take the UAE Repose-7 test, dup it over on Repose-8, same UAE configs, upgraded Repose. Run it for both throughput, stress test and response time. Compare results to that of Repose-7. Present in Dev Meeting showing as much detail as possible.
User access events, functional test template, has been performance tested for Repose 8.
Performance testing overhead and throughput, along with testing criteria and configs are documented on wiki.
Results are presented in dev meeting.
Document findings on public wiki.
IF this is possible and necessary, we'd pair with Identity, figure out their UAE Identity configs, run perf 8 including Identity configs. If team feels it's not necessary, given the configs are very similar to configs used in UAE-8 above, then we can omit this part.
