I have run the test on 10.1 over the weekend. The VM seems extremely slow after running stress2 for two days, is this expected? Is it slow only while the test runs, or does it remain slow after a test iteration completes? The tests are intended to push the system to its limits, so I'm not surprised that the system is slow while certain tests run. It should return to a normal state after tests complete though. > My question is > 1. How long should I run the stress2 test? There's no set time, but a couple of days of run time seems reasonable to me. I hope others who have used the stress2 tests to find new panics or other issues can comment on their experience. > 2. Is there any clear test result shows whether this test passes or not? There's no clear "pass" report; a test "failure" will typically be a kernel panic. Although "the VM did not panic after two days" may not seem as satisfying as a test that prints "PASSED" at the end, it does provide valuable coverage.
