Read over your thread, did you happen to see anything for sensor platform snmp or zone on your testing?
My setup is a HA on a yellow, and seeing consistent time delays for various items on startup.
The affected platforms would be different on every install depending on load order and which integration were configured because the loop was blocked and whatever else was being loaded would lose the race and get blocked.
Same issue here on startup:
