Python • Re: MQTT on Raspberry Pi 3B+ - Subscribe two different topics with Python

Is it possible that two simple MQTT subscribing Python scripts could not run along without blocking each other?

There should be no blocking.
As you did not post your code, some general remarks
- follow the examples, see https://pypi.org/project/paho-mqtt/#getting-started note the mqttc.loop_forever()
- perhaps there is a problem with the influx database connection. For a test, bypass the database access and check if you still see delay.
- perhaps set a distinct client_id in mqtt.Client() constructor in each of the programs.
