It seems CPU utilisation columns and graphs don't take the cores' clock multipliers into account.
As a result, System Informer falsely suggests that the CPU works closely to 100% (therefore is near-congested), even if the multipliers are, e.g. at 11 (1100MHz), with a maximum of 24 (2400MHz).
So, while CPU utilisation is correct for the CPU's given clock, it can be far from its actual capability, allowing for the wrong impression.
Windows Task Manager and Mark Russinovich's Process Explorer don't have this issue. So CPU utilisation values are, more often than not, significantly different among SI and them, adding to the confusion…
