Subject: [THIN] Re: XenServer Slowdown
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
