How to create Dedicated Queue for Inbound Transmissions?

Summary:

How to setup dedicated inbound queues & threads for Tracking Events being received from different systems?

Content (please ensure you mask any confidential information):

We receive Tracking Events from 2 different systems, both of them have different set of information.

One of the system is an external visibility service provider & the second one is an in-house application.

For the in-house application we would like to create a dedicated Inbound Queue with its own set of dedicated Threads. We want to do this setup because the Tracking Events from the in-house application is posted once in a day in bulk & we receive about 4000-5000 tracking events on daily basis which hits the performance of tracking events from external system as well. We are in now going to extend the scope of the tracking events being received from in-house application & are anticipating to get about 8000-9000 per day.
