That's kind'a as expected , based on my experience when upgrading to Plus 23.01
That's also based on FreeBSD v14
My home boxes uses i5-5250U , that CPU is to old to use the new "Speed/Power stuff" so those behaved as usual, using the "Old Power settings"
But my i3 test box was "hit" , and was what i described in the thread i pointed to.
