Only E-cores utilized when Matlab is minimized

How can I get Matlab to use all cores when Matlab is minimized to taskbar?
My set-up is as follows:
- R2021b Update 2 (9.11.0.1837725), 64 biy, December 14, 2021
- Windows 10 Pro, 21H2, ver. 19044.1741, 64-bit
- 12th Gen Intel i7-12700K
I get the below CPU-utilization in Windows Resource Monitor. Allocated cores are set in Windows Task Manager.
20 cores allocated, Matlab maximized; avg. cpu = 23.5:

20 cores allocated, Matlab minimized; avg. cpu = 10.8 and only the 4 E-cores are used:

16 P-cores allocated, Matlab maximized; avg. cpu = 7.4:

16 P-cores allocated, Matlab minimized; avg. cpu = 7.6:

To utilize all cores, I most have Matlab maximized and visible to the eye. It means I can only run one Matlab session and not use the computer meanwhile.

Windows 10 cannot handle the E/P cores as efficiently as Windows 11, as far as I know.
Where does the featuer "visible to the eye" come into play? What happens if you move the Matlab Window out of the monitor? What about reducing the size until the window does not bother anymore?

Hello Chris,
According to my understanding, you are experiencing performance issues with MATLAB on Windows 10 while using an Intel i7-12700K processor. Since it is recommended to use Windows 11 with 12th Gen Intel Processors, I would suggest upgrading to Windows 11 to resolve most of the CPU performance-related issues.

Hi,
I'm facing the same problem as you. Did you by any chance make the update to win11? And did it fix the problem?
Thanks in advance
