We have one ESXi 5.5 host running on a HP Proliant ML350 G6 E5520 with two CPU's and 64GB RAM. We are using local storage. 6 x 300GB SAS in RAID5
There are 3 VM's running on this host:
1. SBS2011 - 4vCPU (1 socket, 4 cores), 22GB RAM, VMXNET3
2. Server 2008 R2 (SQL) - 2vCPU, 8GB RAM, 1 NIC
3. Server 2008 R2 (Terminal Server) - 2vCPU (2 sockets, 1 core), 20GB RAM, 2 NIC's (one E1000 and one VMXNET3)
I've just been assigned the task to monitor the performance of the Terminal Server as users are complaining of random freezes.
First thing I noticed is that the CPU usage on the Terminal Server is constantly arround 70% with random peaks to 100%. Checking the cpu usage for the VM in the vshpere client also shows the same high cpu usage with peaks to 100%.
The CPU usage of the host is running an average of 30%
Checking the process tab in Task manager on the Terminal Server shows that the process winword.exe for one user is running at 50%. (Office 2010)
There are +/- 15 simultaneous users on the Terminal Server.
WSRM is running on the terminal server.
I could really use some suggestions in further troubleshooting this issue. I would like to know if the server just isn't up to the task.
