I can see why. I think we can change the format summary a bit and have one line per CPU only: Allocation Deallocation Page Add Remove RemoveObj/ Page Add Remove RemoveObj/ CPU Fast Slow Alloc Partial Partial SlabFrozen Fast Slow Alloc Partial Partial SlabFrozen 16000 111953360 1044 272 25 86 350 111946981 7423 264 325 264 4832 In addition, we can probably add some sort of option for determining how many CPUs you're interested in seeing (sorted by CPUs that have most the activity first).
