Performance issues in Session State

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:

• Latency and Throughput and Redis Configuration - https://redislabs.com/redisinsight and https://redis.io/topics/config
• Connection Pooling Best Practices and Detecting Connection Leaks - https://stackexchange.github.io/StackExchange.Redis/Configuration.html#connection-pooling and https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/connection-management
• Session State Management and setting in ASP.NET - https://docs.microsoft.com/en-us/aspnet/web-forms/overview/data-access/working-with-data/using-session-state and https://docs.microsoft.com/en-us/aspnet/web-forms/overview/overview-of-aspnet-session-state
• Redis Locking Mechanisms and Concurrency in .NET Applications - https://redis.io/topics/distlock and https://docs.microsoft.com/en-us/dotnet/architecture/modern-web-apps-azure/common-app-design-patterns#handling-concurrency
• Redis Versioning and Update - https://redis.io/topics/cluster-spec
• Configuring Redis Session State Provider - https://github.com/ServiceStack/StackExchange.Redis#redis-session-state-provider
• Redis Client Library - https://stackexchange.github.io/StackExchange.Redis

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.
