Have you had a look at them again? Activity indicator your Mac, and did you notice the “PerfPowerServices” process? No problem, because in this guide I have summarized the most important information about the macOS background process. The good news first: it is not um malicious software. So you don't have to worry if PerfPowerServices appears in the list.

The PerfPowerServices process on the Mac: Overview of system performance data
According to the official description, the macOS PerfPowerServices process manages structured log archives that enable control of system performance and related performance data. The main task is to provide information about the power consumption of the system and individual hardware in order to work out energy-saving operation. The Daemon is directly subordinate to the first process required to run macOS, launchd.
Another task of PerfPowerServices is to check internal peripherals and prepare them for use. An example of this would be the microphones and speakers in an iMac or MacBook. Their required power supply can be checked before they are used, so that they can be activated and used efficiently by the user without consuming too much power. The macOS PerfPowerServices background process is one of Apple's many efforts to make the Mac work as efficiently as possible.
High CPU load due to PerfPowerServices on the Apple Mac
I didn't find much information about the problem that PerfPowerServices constantly leads to a large CPU load of up to 100%. If the daemon brings your Mac to its knees, you should first restart it. Turn off the Mac completely, wait half a minute or a full minute and then turn it on again. Wait a bit before starting programs and accessing websites; It is possible that the process will then start again.
Another recommendation I've found is to remove most external peripherals (except the monitor, mouse and keyboard if needed) and then start the Mac in Safe Mode. Here, individual problems can be isolated so that they can be solved more easily. Some who reported CPU issues with PerfPowerServices resolved them after multiple reboots. In addition, they often only occurred if the Mac was not restarted for several days, but was only put to sleep when it was away. More about the different approaches here: Turn off your Apple Mac overnight or leave it in sleep mode?
Conclusion: PerfPowerServices is a macOS daemon
If you can find the PerfPowerServices process in the macOS Activity Monitor, then you don't have to worry. Because it is part of the standard features of the Mac operating system. Thanks to PerfPowerServices and the associated processes, the Apple Mac can use its individual hardware components more efficiently and thus reduce power consumption and ensure longer battery life. A high CPU load should only occur in exceptional cases and in most cases can be solved by restarting.
