# Service Bus Testing Report

We've used his SDK to test service bus using python : https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/servicebus/azure-servicebus/samples

This is a summary of the test report :
* First test were  run using the sync_version of the Python test sample and a Standard Tier Service bus.
 Test were ran mostly on one or two subscriptions and performance were poor 10msg/s

* Using premium tier same test and premium tier we got same results 10 msg/s

* using a DOT net Benchmark tool slowly upgraded perf but we didn't dig into the code around 20 msg/s

* Then using asyng call with the python sdk (local computer) we managed to send 200 msg/s

During all sending tests we will use 500 as the number of messsages that we try to send
