Restoring Image to Dell GX620 Takes 40 Hours

We are running ZFD 7 SP1 on a Netware 6.5 SP 5 box. We recently upgraded
from ZFD 6.5 SP2 to 7 and then 7 SP1 because of this imaging problem.

I can create an image and store it on our ZFD Server in about 14 minutes.
However when I try to restore the image to another Dell it takes almost 40
Hours to complete. This is a slight improvement over the 48 + hours it
took to restore an image using ZFD 6.5 SP2. The only solution I found
while searching this issue was the ZFD Hotpatch 2 for ZFD 6.5 SP2 which was
supposedly incorporated into ZFD 7 SP1. I am about to open a support
incident with Novell if I can't find a solution soon.

Please help!!!
