Hi.
We are running a .Net Framework 4.8 mvc web application with redis session state setup. We are experiencing performance issues and the profiling we have done indicates that session state, specifically GetSessionStateItemAsync, is waiting for long periods of time.

Things we have done to resolve the issue:

  1. Increased network bandwidth on redis cache
  2. increased the number of available threads
  3. decreased the size of items stored in redis cache (not related to the session values)

But so far these changes have not helped.

The profiling revealed the following on a few of our slow running requests:

Any ideas on how we can identify the source of what is causing these performance issues would be great, thanks

    Hello Danielle Schlie,

    Welcome to the Microsoft Q&A and thank you for posting your questions here.

    I understand that you are having performance issues in Azure Cache for Redis Session State.

    Since you've already tried several optimization strategies, issues with Redis session state in a .NET Framework MVC application can be complex. But here I will give a few more areas to identify and address the source of the problem in the links:

    I am sure that one of these lists will definitely solve the problem, but if you have a specific error cod in the log, kindly let us know.

    I hope this is helpful! Do not hesitate to let me know if you have any other questions.
