Dave, after playing with the unbelievably slow backups on my MacPro, I don't get why the prebinding is an issue for overall speed, as that is in the final phase and not performed on non-boot drives.

Maybe this will be helpful:

Today my now 9+ hour Time Machine drive clone was still percolating at 10 this morning, so I popped open Activity Monitor and saw that SDCopy was eating 87-100% of a single core with 2 threads. I'm running SD 2.6.1 right now to clone my MacBook Pro drive under 10.5.8 before upgrading it to 10.6 later today, and SDCopy is only eating at max 15% of one core with an average of around 1-3%. That puppy really beats itself up under 10.6.
