Hi James,
What post Windows 2008 SP2 hotfixes have been deployed?
Is XenApp 5 at FP3 level? If so, what post XenApp 5 FP3 hotfixes have been
deployed, if any?
Why is your mandatory profile on a share and not local?
Is your file server 2003? If so, SMB 1.0 may be a bottleneck, and you may need
to tune.
Which HP Support Pack has been used?
It's much harder to troubleshoot user profile load issues under Windows 2008...

HP SIM reports 31.9GB of ram available/addressable.....

XenApp - Correct
Windows 2008 SP2 - not R2,
Windows system reports 36GB in system properties, HP SIM reports 32GB of ram
addressable / available - WTF? - chasing this up for further details.......

I'm going to out on a limb and assume that you are referring to XenApp and not
XenServer.
First question, why Windows 2008 Standard x64?
Windows 2008 R2 is going to be a much better choice, especially
if you are running this directly on new hardware.
Second, Standard edition only support 32 gigs and you're
showing 36 gigs
Also, which metric is sitting at 25% utilized?

Greetings
(sorry about last unfinished email went to save to get more info and clicked
send - sigh)
We are having speed issues with our XenServers
* Brand New builds
* Deployed with Altiris
* Xenserver 5.0
* Windows 2008 Standard 64bit
* 36GB RAM
* Dual CPU, 8 Core processors X5560 2.80Ghz
* Appsense EM and PM (with citrix CPU and memory management disabled)
* Sophos AV
* HP Hardware DL380 G6 with teamed nics
For normal operation we are getting 25 second login time (to desktop)
After approx 30 users (or 2 days without a reboot), the performance drops to
1-1.5 minutes just to log in, everything sluggish, cant open task manager even
though multiple taskman icons appear in systray.
No performance issues on the systems themselves, all sitting around %25
utilised. (CPU, MEM, DISK etc)
So far:
We have disabled Sophos, no result
disabled Appsense, no result
turned on VT instructions for CPU in the BIOS, no result
turn off TCP offloading for the NICS
HW firmware for Servers / patching (latest PSP)
Software for OS and apps / patching
Any one seen anything like this already? apart now from bringing up a VM host
to eliminate hardware or a full manual rebuild and testing at each stage of the
build process - we are starting to run out of 'obvious ideas'
ANY assistance and advice greatly appreciated!
JAMES
