I'm using Apple System Image Utility (SIU) on Snow Leopard 10.6.2 and I am rather disturbed it takes over Three hours to make a Netrestore or Netboot image.

I'm using as the donor machine a brand new iMac and as the imaging machine a brand new iMac connected using target disk mode & Firewire 800. The hard drive size and subsequent image is about 8GB. To restore the image over the network takes about 4 minutes.

Given that Norton Ghost will take an image in about 5 minutes (or less on newer machines) over USB2, why is the Mac over an order of magnitude slower?

Anecdotal story: I had to restore a 6 gig image to a USB flash drive that's capable of 35mb/s and it took 3 hours. I used Snow Leopard's Disk Utility. I would also like to know why this performance was so poor. Note: the image contained several large files, not lots of small ones, so I imagine that latency of the USB drive is not a problem. –  ta.speot.is Jan 22 '10 at 6:31
