How to isolate latency issue for Azure Storage Account

Hi,

Thanks for reaching out to us!

Low server latency and high E2E latency, would indicate that there is some misconfiguration/network issue at client side. The common attributes that can be checked to see if there is performance issue with the client application/VM are:

1. High CPU on the client: When you are running the application, check if there is spike in the CPU of the client machine. If the CPU is higher than expected, it will result in performance issue for the application and in turn increase the latency value.
2. Low available memory on the client: Check if you are running low on memory on the client machine.
3. Running out of network bandwidth on the client.
4. Misconfigured client application.
   
   

You would need to check at application and network side to what is causing the latency. I hope this helps you. 

Thank You!
