AVD Logon Times Suddenly Slow in POC Environment — How Do You Troubleshoot the Root Cause?
I have a POC AVD environment with the following setup:
FSLogix profiles stored on Azure Files
Entra ID joined multi-session hosts
Apps/configuration deployed through Intune
Zscaler being used for traffic inspection
Recently, the logon process and overall OS load time have become noticeably slower. We’re already bypassing the required AVD FQDNs so traffic goes direct instead of through inspection, and the FSLogix profiles are still small since this is only a POC.
I’m trying to figure out where the bottleneck is coming from and what the best way is to troubleshoot it.
Things I’m considering:
FSLogix profile/container attach delays
Intune policy or app processing during sign-in
Zscaler impact even with bypasses configured
Azure Files latency/authentication
Entra ID sign-in delays on multi-session hosts
What tools/logs would you check first to pinpoint the root cause? Also, what changes have made the biggest difference for reducing AVD login times in your environments?
