Netboot: Appliance VM vs MacMini

Hello,
We have been netbooting our imaging systems off of three Mac Minis. I was hoping to speed up the process by implementing the Netboot/SUS appliance. Our VM infrastructure uses XEN, so I extracted the OVF file to get the VMDK and created a XEN VM using that. I even went in and verified that the VM was using the paravirtual drivers, to make sure it was running optimally. When I finally got to netbooting, the startup time for a MacBook Air went from 2.5 minutes up to 7.5 minutes. Not the direction I was hoping for.
I guess we'll be sticking with the Mac Minis for a bit longer. The main issue I was hoping to eliminate was that the boot time gradually increases, until it won't image. After rebooting the Mac Mini everythign goes back to normal. For a while. Then the slowdown begins again. I've tried scheduling the Mac Minis to reboot every evening, but they frequently hang during the reboot. At that point, the only recourse is to hold down the power button. Wait a bit. And power back up.

We use the NetSUS appliance in a lot of cases and the speed is ok. No real difference between the VM and Mac minis from what we've seen.

Are all the other variables the same (network link speed, RAM, CPU, .nbi image)?
