Novell ZENworks Configuration Management 11.2 Imaging


Restoring a base image using multicast to a single device can take 3 or more times longer than restoring the very same image through unicast imaging.


This is related to the current multicast imaging implementation design.

Additional Information

With the current imaging multicast implementation, single device restore performance can be very much slower than compared to unicast imaging. It makes sense performance-wise to use multicasting for mass restoring like 5 or more device, primarily to limit the required network bandwidth. Also unicast imaging restore performance likely drops with 8 or more simultaneous imaging sessions.

Multicast imaging performance can not be substantially improved with the current product design.
