How many backgrounder processes can be configured on a single node?

The correct answer indicates that the maximum number of backgrounder processes that can be configured on a single node is dependent on the physical cores of that node. By configuring up to half the number of physical cores, you can ensure that the system remains performant while allowing for multiple simultaneous background tasks to be processed, such as extract refreshes or subscription email deliveries. This setup helps maintain optimal resource usage and avoids the potential contention that can arise if too many processes are run at once.

Having a configuration based on physical cores allows for a balance between performance and resource allocation. The number of background processes needs to be limited to ensure the node is not overwhelmed, hence the guideline of utilizing half of the physical cores helps to strike that balance effectively.

This approach does not take into account the total number of logical CPUs or virtual cores, as those can vary significantly from one environment to another and may not reflect the most effective configuration for background processes. Therefore, it is essential to focus on physical hardware specifications to determine the appropriate setup for backgrounder processes.
