In short, on my Windows computer GeoServer 2.20 generates a steady 15% CPU load even the server is idle when it comes to any GIS services.

I checked a few older versions and GS 2.16 shows much smaller numbers, about 5% CPU.

Andrea Aime made a quick analysis and suggested that the OSHI library is responsible for the load.

If I understood right something may go wrong with detecting the processor type. This is what the Windows systeminfo tells about that:

System Type:               x64-based PC
Processor(s):              1 Processor(s) Installed.
                           [01]: Intel64 Family 6 Model 142 Stepping 10 GenuineIntel ~1910 Mhz

The jstack outputs from both GS 2.16 and GS 2.20 are attached.
