Mac Studio Spiking Rosetta or Native, plugins or no plugins

As the title says, N12 will randomly spike on my M1 Max studio, wether or not it’s in native or rosetta. Wether or not I have plugins.

I make sure to not have safari or other apps open.

How well known is this issue? I have VSL servers with are older x299 i9-9940 cpu based systems. Would I expect, all things being equal, no or less spiking on one of those machines?

During playback/record or also in ‘rest’?
I have not seen this myself on similar mac, so maybe a hardware defect or a driver (audio interface) issue? What is your setup?
