I post numbers all the time. > Yeah I know - it just so happened that you got *worse* performance from Ingo's balance-on-clone than by simply decreasing the balancing interval just now :P Although it is probably just because balance-on-clone is not tuned well. I've said all along that it will probably be a good thing to do if it is implemented correctly, but 1. we need some good numbers, and 2. let's not stuff it in at the same time sched-domains goes in because it is a fundamentally different concept.
