poor IIS performance on VM

Hi Experts,

we have converted a old server WIN2008 to a VM.
All works but the IIS performance is poor.
The users from outside can connect but very slow and sometimes with interrupts.

Do you have any ideas ?

The VM has 4GB RAM and 8 vCPUs. It is a 32bit system.
We use VMWARE 6.0 with NFS storage on NETAPP.
Before the migration (P2V) the IIS was much more quicker.

Comparing physical versus virtual servers, is never a good idea, performance will ALWAYS be better on the physical!

But if it causes performance, or service issues, in your case, this is not good for service.

But 8 vCPU sockets could be excessive ?

How many concurrent users access the server?

Why have you decided on 8 vCPUs ?

also how are these vCPUs provisioned, as sockets or cores ?

see this recent Question on EE, I answered

I changed back to 4 sockets vCpus
Some old services also took performance of one complete core.

Now is better.

I have to wait until tomorrow, when user connect to it.
