We have deployed a small VMWare View solution for Admin Staff, Accounting and CAD / Drafting users. We currently have 21 VM's running and received daily complaints about performance, some days better than others but overall well below the performance level of an appropriately configured Desktop. We are either needing to end the production use of this system and return back to standard desktops or add an additional VMWare view server and soldier on, hoping we can find the cause of the low performance.
Here are the spec's.
Server Running VM's:
Dell PE R510, 2 x 6 core Xeon 5670 CPU's running at 2.933ghz, 64gb of Memory, 1.81 TB Raid 5 Storage using 6 SATA 6g 7200RPM drives, 4 x 1gbit Network cards
VM Config:
Windows 7 32bit, 2 CPU's and 3gb memory per system, we have 3 Linked Clone pools for Accounting, Admin and CAD specific software installs.
I just cannot see were the loss in performance is. Sometimes users sessions hang for a few seconds when they select various functions in office or AutoCad, then the system becomes responsive again. Other times the screen quality degrades a little before clearing up. For some office programs take an excessive amount of time to load and become available. Sometimes login or general file / network access is slow, folder contents lists taking prolonged periods to refresh or display contents. Sometimes functions such as printing and Plotting take excessive amounts of time before their respective dialog boxes appear.
I have attached screen captures of our performance stats for review. Any assistance would be most welcome.
