Terminal Server & XenApp Tuning Tips
23 May, 2009 (84160 reads)
Working in SBC environments for some years now I've used some best practices documents like the well known Methodology In a Box (MIAB) from Rick Delingher.
These documents, although really pertinent, are now quite outdated and do not include the latest OS and XenApp releases.
The purpose of this article is an attempt to summarize all Tuning Tips I've found (and also that I'm using) and describe the target operating system / XenApp version(s) they're working for.
Do not hesitate to give us your comments for this Article to be updated with your experience and feedback.
Please note that these informations are provided "as is" and that using these tips is at your own risks.
Please also Note that all REG_DWORD values are provided in decimal format.
All Registry Hives are provided for x86 platforms. For x64 Platforms, do not forget to add "WoW6432Node" if hive is in HKLMSoftware.

Along with these registry settings, do not forget to install UPHClean (W2K / W2K3) to manage profiles at logoff and ensure no lock will remain leading to profiles corruption and long logoff times.
UPHClean is natively embedded into Windows 2008 and later (User Profile Service).
Also, as a Best Practice, it is recommended to Disable Data Execution Prevention on Windows 2003 and Windows 2008.
To do so, you have to modify the boot.ini file or use one of the following command line(s)
- For Windows 2003 : bootcfg.exe /raw /fastdetect /noexecute=AlwaysOff /ID 1
- For Windows 2008 : bcdedit.exe /set {current} nx AlwaysOff
Additional Windows Explorer Tuning
The following Tuning Values are an extract from an Helge Klein blog post and were added on June, 1rst 2009 (Thanks to Laurent Falguiere for pointing these settings in his comment)
Warning : UseDesktopIniCache can generate a Delayed browsing (5 sec) with redirected My Documents on Windows Server 2003 in some circumstances as stated in Ingmar Verheij article so as usual be careful when using tweakings !

Just posting this as many of our optimizations came from this site for our Terminal Server environment. Beware!

Sorry for the side effects you've encountered.
I've never seen such a problem with the Cursor Blink Rate being modified in years of use.
Thanks for your feedback.

Pierre
I remeber from the old Methodology in a Box from DABCC that the HKLMSYSTEMCurrentControlSetControlPriorityControl Win32PrioritySeparation should be set to backgroung process (value of 24) rather than foregroung (value of 38) because of the way sessions are managed. would it be possible to investigate a little more on that settings? BTW it is possible to change that setting via Start -> Settings -> Control Panel -> System -> Advanced Tab -> Performance Options
-> Set Application response to ‘Background services’
Regards,
FD
Thanks for this post.
For me HKLMSoftwareMicrosoftWindowsCurrentVersionExplorerVisualEffects
doesn't work.(option box doesnt changed in advanced settings)
But I try in HKCU, and here it works fine. (option box are well Displayed in advanced settongs)
Do you think it's just the display or settings are in HKCU ?
Bye
Vincent
