das ist auch mal interessant für die Leute die immer % Angaben der CPU als Richtwert nutzen:
For systems where power consumption and heat are not an issue, but maximum performance is, it may be desirable to disable CPU Parking. The fact is that even if unparking is near instantaneous, CPU utilization usually occurs in very brief bursts, something I mention frequently. If you look at your CPU utilization and see 15%, that is actually the percentage of time the CPU was active within a relatively large interval (usually 1 second). Actual CPU utilization most often occurs in micro-bursts where the CPU is fully consumed for a few nanoseconds or microseconds. You want those bursts to execute as fast as possible, and this is why all power saving technologies, including frequency scaling, incur *some* performance hit. This is also why a faster CPU does matter, even if you typically don't utilize 100% of available CPU time over a larger interval.
I often watch in the Resource Monitor as it parks cores while system load is nearing 50% of total CPU time. This may be why they provided the newer, and even less documented, option "Processor performance core parking over utilization history decrease factor". This option has *something* to do with how aggressively the Windows scheduler will park CPUs based on over-utilization of parking in the past. In other words, if it has been parking them too often, it will 'ease up'. This *additional* value related to core parking has the description: "Specify the threshold above which a core is considered to have had significant affinitized work scheduled to it while parked". Sadly, since there is no documentation on this power option, I am not yet going to comment more on it - yet. I will say it defaults to 2 and has a maximum of 1000. There are also additional new values such as "Processor performance core parking increase time". I'll leave it to the reader to explore these undocumented advanced values at their own risk!
es geht ja um die micro burtsts, selbst wenn die CPU bei 20% (typische tool Anzeige) ist - kann es sein dass sie immer wenn sie gebraucht auf anschlag bei 100% läuft.

einfach den wert auf 0 ändern
kann man das auch in windows selbst einstellen im energieprofil. dann braucht man keine dubiose SW.
