It's such a shame they removed UserEnvDebug log in 2008.

I've found 2008 to just be slow in general in comparison to 2003 but there are 
a couple of things to speed logon times.

Switch GPSvcDebug on on the terminal server.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Diagnostics]

Not quite as feature rich as UserEnv but may highlight something.

Clear down C:\ProgramData\Microsoft\Group Policy\History especially if your 
running Group Policy Client Side Preferences, exclude in AV if your scanning 
any file.

Be careful of printer drivers if doing printers via GP CSP

 Obviously mandatory / hybrid profiles help.

14seconds isn't bad in 2008.

Theres some group policy information in the eventlog but nothing like the 
userenv debugging you got with 2k3.

Ive tried turning all group policies off which didn't really make a difference.

I seemed to get better performance when disabling client mappings, especially 
printer mappings, but nothing to shout about.

Am I gonna have to accept this and just say "Sorry, thats 2008 for ya, weve 
upgraded you to the latest OS and given you a slower, but much more reliable

One thing I noticed in deploying XA5 was how much extra resource it seemed to 
use *before* any punters were on. Did you do some load testing before your role 

You could do a logon trace - maybe look at the timings ? if you've still got a 
w2k3 box you could run a userenv.log trace w2k8 sticks the trace into the event 
log iirc. Maybe there's a registry/script change/update that's hosing the logon?

I've done a few upgrades recently moving people from 2003 to 2008 SP2 and 
latest Xenapp.

Nearly every time the users have noticed a longer login time.

One company went from 7 secs to 14 secs (i know it's not a long login time but 
it has doubled!).  We basically replicated their Windows 2003 setup 
(xenapp\DCs\File\Print\SQL) but have everything on Windows 2008.

Most things work ok but the login times are killing me, I'm having to explain 
why this is without really knowing why there is such a difference.    Anyone 
else notice this?  Any tips?
