Heh, indeed! :)
Ive never chastised (lightly or otherwise) a customer with RG's that dont balance out perfectly...we discuss it, but if a disk purchase is not in store to solve a perf issue Im consulting over, I dont suggest that capital and effort be taken to resolve it at that time. It's rare, IMHO, to see that overhead manifest itself in the user space. You have to exhaust the CP engine to do it, then even so, you're likely still left with a sizing challenge to resolve. (Legacy HW servicing new user loads, etc)
I think that's a reasonable position to take.
Later on..a few disk adds and a few injections of reallocate to the patient are in good order.
Yup.
