NServicebus - One endpoint multiple handlers threading

Question

I have two endpoints.

Endpoint 1:

• HandlerForMessage X
• HandlerForMessage Y
• HandlerForMessage Z

Web endpoint: - No handler

Answer 1

Unless it has changed since I started using NServiceBus, the "unlicenced" version only runs 1 worker thread so it only processes 1 message at a time.

You can alter this in the config by altering the NumberOfWorkerThreads value on the transport, however you need a valid licence in order to increase the number above 1.

In NServiceBus v4, you need to configure the MaximumConcurrencyLevel value on the TransportConfig:
