I'm using ZCM 10.3.1 with VMware vSphere ESXi 4.1.

The imaging process on a vmware virtual machine takes twice the time from running the imaging process on a ohysical PC.
I've checked all the Vmware components (Network / Storage) and I found no bottelnecks.

are there any best practices while using ZCM with VMware?

Thanks for all replys!
