This may be a use case issue. I have a zigbee door contact that communicates to HA through Z2MQTT which turns on the light when the door opens. It turns on so fast that my wife didn't believe the light wasn't already on until I made her open the door from the inside. It is instant for all intents and purposes. So this delay may be relevant to the setup, more than MQTT itself.
