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!
