Kubernetes loads only one thread up to 100% or two threads totaling 100%?

[info-infoman]

I launched your project in Kubernetes on the truenas platform, but when I try to run the installation of a heavy program, the msiexec process is not distributed across the processor cores. At the same time, on a virtual machine where a full-fledged Windows 10 is installed, it works fine:

I tried different settings, but when creating containers with heavy installations, either only one thread is loaded, or two with a total load of 100%. No distribution among other streams. CPU Limit = 16000. Maybe someone knows how to configure Kubernetes so that it spreads the load across all threads?
