We have below statistics : (output is trunked) MMB CPU-0 and CPU-2 seems working at all time but CPU-1&3 looks ideal. How can we fine tune this?

Hello - there isn't anything to "tune", as you seek. What tool are you using to see this data?

Incidentally, we removed such info from the likes of HDCA simply due to the fact that it was confusing to customers when the individual values of each core are questioned. It is not necessarily a bad thing to see a core max’d at 100% as well.

 

A better measurement on system health is to look at the overall load calculation and not the individual core values. If you are having a performance concern, please open a case with GSC to help gain better insight into the workings of the server(s).
