i did not quite understand the down differential part. Can any one
explain it.
What role it plays while scaling down. because if the load is less than (upthresold - down_differential) it scales down everytime the sample duration. this is what i understood.
thank you.
It is to avoid ping pong of freq.. so we decrease freq when we r sure that freq isn't going above upthresh due to minor correction of load in near future..
