Thanks a lot for the feedback. I'm running the system in a PC with a Ryzen 5 5600x, so, seems I'm pretty limited in hardware capacity. Seems i will have to upgrade to a better CPU model.
Regarding the license issue, I am running zOS as a hobby and without any commercial purposes whatsoever, so I hope there will be no problem. Thanks again and have a great day!

I was observing this as part of a z/OS v3.1 update, and a hour after the IPL, while everything else was checking out fine, I noticed z/OSMF was still hogging all the CPU it could get. My experienced peers said that was common, and this shop needed a bigger box and a zIIP.
