Slow login/Performance App volumes with Symantec client installed

We`ve been troubleshooting slow login and poor application performance on our Non Persistent VDI for a while now. App Volumes and Symantec Endpoint Protection doesn`t seem to like each other.

Without a SEP cliënt installed everything is performing well and user experience feels like a persistent VDI. When SEP is installed including all obvious exceptions and even using the virtual image exception tool no significant change in performance is noticed. We`ve been testing all scenario`s disabling components of symantec. Only disabling "Application & Device Control" seems to improve login and application performance.

Login times :

Symantec all components on + 3 Appstacks                        2,36 Min

Symantec Application & Device Control off + 3 AppStacks  2,06 Min

Symantec all components on + 1 Appstack                          1,51 Min

Symantec Application & Device Control off + 1 Appstack    1,25 Min

No Symantec cliënt installed + 3 Appstacks                         0,50 Min

Anyone dealing the same issues? We can`t skip Symantec or move to another AV vendor. (large enterprise)

I realize that FSLogix is a different application, but maybe this KB that was just posted by Symantec would be of assistance?

Slow logins with FSLogix and Endpoint Protection

Stating that it is Windows Defender and SEP fighting over the files. I don't have any noticeable slowdown with or without SEP (14.2 RU1 MP1) installed on our image on 1809 LTSC or 1709. So maybe that could be your issue?
