# Useful Information

ProtocolServerStartupDelayInSecs is a new optional configuration property that is recommended to be used only in installations that include more than 150 controllers.

By default, this property is disabled and all protocols start simultaneously. When configured, ProtocolServerStartupDelayInSecs introduces a delay between the startup of different protocol types. The recommendation is to set a delay of 5 minutes (300 seconds), though the optimal value may vary depending on the mix of controllers in the system.

Enabling this setting triggers a staggered startup process. As a result, it may take up to 30 minutes for the service to begin reading from all controllers.

To ensure system stability, particularly in large deployments with numerous units and high-frequency data collection, it is strongly recommend to set this delay. It helps prevent potential overload of RabbitMQ during the startup phase.
