Kolibri 0.15.x running on Windows 10 - Python high CPU utilization

[pcenov]

Observed behavior

In Windows 10 one can notice that when running Kolibri 0.15 this is causing high CPU utilization of up to 35-50% even when Kolibri is not in use.
This was initially internally discussed here: https://learningequality.slack.com/archives/CAUTAU14Y/p1665777085135879
And is now reported in the community forum here: https://community.learningequality.org/t/python-high-cpu-utilization/2665

Expected

It should be further investigating what is the root cause of the issue and the CPU usage should be minimized.

Steps to reproduce the issue

1. Install Kolibri v0.15.x on a Windows 10 device.
2. Monitor the Python CPU usage.

Usage Details

Windows 10 and Ubuntu 20 - Chrome, Firefox

Suggested by @rtibbles:

The possibilities that come to mind are:

• The background task runner is somehow running amock.
• The magicbus thread manager is running amock.
• Something funny is happening with the pingback task.
• Version of Python used if installer is signed by Github action vs manually in the signer VM, and whether that might mean that the Python cryptography package had its C extensions installed or not.

@pcenov and @radinamatic - as you begin integration testing for 0.16, can you confirm if this continues to be a problem on windows 10 for the newer release? Thank you!

Hi @marcellamaki - I confirm that this is still the same in Beta 7:
