Windows machine can not give more than 3-4% CPU utilization.
CPU settings is 75% of the CPU with 100% CPU time.
What can be possibly causing this?

What memory do you have and what are the memory settings in Boinc?

What are the suspend settings?

What tasks are running?

Similar problem. 14 core i7 windows 11 machine. I had CPUs to be used set to 30% CPU time at 60% and the CPU usage would bounce between a few percent and 100 a couple of times per second. I have stopped downloads from SiDock and the problem appears to have disappeared even with percent of CPUs at 80%. I have the machine set to run off of local preferences, and I have CPU and GPU set to run based on preferences.

Got an unexpected spread between WU runtime and CPU time with Win 11, like 70% cpu time compared to runtime. Seems not to be limited to cmdock alone.
Curiously, Boinc on Linux on the same machine does not have this problem. I am am using a i5-13500 Intel-CPU with Win 11 Pro 22H2 and Ubuntu Linux 23.04, respectively.
With Win 11 cmdock is not going above 9% CPU usage per thread, while an Einstein GPU task is using 13% CPU (part-time).

Any idea how to fix that?
Too much wasted runtime an Windows. Should switch to Linux permanently then.
