It is hard to know the overall effect without accurate timings. My personal belief is that on average the total time will drop. But we need timings to know for sure.
I still can't understand why we're focused on reducing testing time.
The longer the tests take, the fewer times they can be cycled. That is a particular problem as a release nears. The release manager often has to delay some action pending the outcome of tests. Not a problem if the tests run quickly and cycle often. But when a test cycle takes 2 1/2 to 3 hours, as was common during the runup for 1.31.0, it adds days to the time it takes to finish a release. --Beman
