I have a physical HP DL 380 G7 server 80 GB of memory, 900 GB storage, 1 CPU (Processor cores per socket 4 and total logical processors 8, with hyperthreading enabled).

Every client (5 guest in total) are working via their own terminal server, connected via a remote desktop gateway and asa 5510 firewall on their own vlan. OS is WIN 2008 r2,VMWare version is V6, with latest HP servicepacks on it.

Memory total is 26 GB used

Harddiskspace used is 576 GB

I gave all the guests a total of (vsocket x cores per socket =) 14 VCPU. But as i can see i have only 8 VCPU available, so am I overprovisoning?

My clients are complaining about peformance and freezing of the Remote desktop they run on. I can also see it sometimes. The screen stops, my ping times are rising to 15-25 ms in 2 seconds and than it disappears again and they can work. (i did this from a terminal server from a client and pinged the firewall and the internet).

Is this because of the over-provisioning (14 VCPU in stead of 8 VCPU available ??) does anyone has a solution or has experience with this kind of slowness in VMWare?
