Orazz from CitrixIRC found a great forum post that really made an impact on our environment. In a nutshell, when using the 2008 R2 Optimization Guide for XenApp and the Citrix Profile Manger, there is a registry setting that causes the UPM to timeout. A lot! After making the changes below, I noticed an immediate improvement in performance of the UPM. Logon/Logoff times have been reduced significantly. I’m also hoping this is going to lower the profile corruption issues that also pop up from now and again. We don’t have many since upgrading to UPM 4.x, but we still do have some.

  1. Upgrade to UPM 4.1.2
  2. Change HKLM\System\CurrentControlSet\Control\FileSystem\”NtfsDisable8dot3NameCreation” from “1” to “0” ( I did this using a GPP object as part of the optimization guide. I simply edited the GPP and changed to “0”)
  3. Backup and delete the keys from “HKLM\Software\Policies\Citrix\UserProfileManager”
  4. Reboot

Upon rebooting I verified the keys were recreated, and the NtfsDisable8dot3NameCreation was set to 0.

Note, some interesting changes in UPM 4.1.2 also. We use “Delete locally cached profiles on logoff”. This process now takes about 3 minutes for the folder to delete from the XenApp server. This is part of the new design. See UPM 4.1.2 in
