2 background workers, 10 Monq workers behavior question

[sferoze]

Hi my question is about this text in the documentation

"This will set up 2 background worker processes. If you are deploying to multiple servers, or servos (modulus), this will fire up 2 workers on each. It will then start up 10 Monq workers on each process."

I understand the use of this package. To setup a function, to be called at a later time on a schedule. It will run this function in a new meteor process so it does not block the current server.

But I am lost when it comes to the configuring the background workers and Monq workers.

I imagine when a job is scheduled to run it would just start one background process. Why is the default set to 2 background workers? And why 10 Monq workers? Isn't monq just to connect to mongodb?

Thanks in advacne for the clarifications
