coreaudio %CPU relatively high w Pro Tools

[whatfools]

Hello friends, I'm looking for information regarding coreaudiod %CPU usage w Pro Tools. There is a large discrepancy between the %CPU usage rate of the CoreAudio daemon on my computer when using Pro Tools, Logic Pro X, Live 10 Lite and Kontakt 6.

The behaviour is as such:

- from clean boot coreaudiod %CPU approx. 0
- after launching Live 10 Lite coreaudiod %CPU approx. 2
- after launching Kontakt 6.2.2 coreaudiod %CPU approx. 2
- after launching Logic Pro X 10.4.6 coreaudiod %CPU approx. 5
- after launching Pro Tools Ultimate 2020.3.0 coreaudiod %CPU approx. 17

Computer is:

Model Name: Mac mini
Model Identifier: Macmini6,2
Processor Name: Intel Core i7
Processor Speed: 2.3 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Hyper-Threading Technology: Enabled
Memory: 16 GB

OS is:

Mojave 10.14.6

Is it to be expected that Pro Tools will use much more CPU time that these other apps, or are there settings adjustments I could make to reduce Pro Tools use of coreaudiod?

Thank you kindly for any help given.
