How to get better performance with Azure ServiceBus Standard plan

I don't manage to get over 14 msg/second with the Azure ServiceBus Standard Plan. I'm running some benchmark tests with the Azure-Sample tool that I found in this question:

The test is done with a ServiceBus resource with a single Queue and all default configurations:

If I read this correctly, you've got the maximum concurrency of one (MaxInflightReceives) with 5 receivers (ReceiverCount). Increasing concurrency and enabling prefetch on the clients will increase the overall throughput. But,

  1. Testing should be done within the same Azure data centre. If you're testing from a local machine, you're introducing a substantial latency that cannot be avoided.
  2. The receive mode used is PeekLock. It is slower than ReceiveAndDelete. Not suggesting to switch, but this needs to be taken into consideration as you're trading throughput for safety by using PeekLock.
  3. The standard tier has a cap on the number of operations per second. In addition to that, your namespace is deployed in a shared environment with entities scattered in various deployment containers. Performance will vary and cannot be guaranteed. If you want to have a guaranteed throughput, use Premium SKU.
