title: Regular throughput troughs in Azure functions requests per second
body: <p>I am running an Azure function in Consumption Plan mode and am seeing regular troughs in throughput as shown in the attached image. I have stripped out all external dependencies such that function execution is predictable, as in, receive single event from event hub, create a new event hub message, and write back to (source) event hub via IAsyncCollector parameter. </p>
  
  <p>While the behavior is not a problem per se, I am curious as to why it exists and if it is specific to the Consumption Plan mode?</p>
