Why is it recommended that background workers run on the web server?

[davidharting]

This issue is related to the documentation on background workers.

I am opening this issue hoping to learn more about the last two sentences:

The buffalo.App#Serve method will, by default, call the worker.Worker#Start method for the registered worker. This will also call the worker.Worker#Stop method when the application is shut down. This is the recommended approach for applications.

This text is clear to me, but I would love to know the reasons for the recommendation.

This would particularly enhance the documentation, because I believe this recommendation may violate many readers expectations. For myself, I was surprised that it was not recommended to run workers on a separate node as I assumed it would be generally better to leave as much compute as possible for serving web traffic.

I am not questioning the recommendation or suggesting it be changed, but am simply eager to learn the motivation for the recommendation.
