The test prints benchmarks together with any deviations from the previous runs. Is there anything else to report? Yes, but not in the test output.
A performance test is a perfect candidate for daily or continuous testing. Make sure you notify developers about any changes in performance, good or bad.
I personally take the complete output of the test and report that. It contains enough information for a human to assess performance. Your choice might be different, so I won’t talk further about reporting here.
