Yet Another Slow Copying Issue Thread

I'm having the same problem copying a fresh sparse image over to a 1TB WDD MyBook Studio. I realize that people are having troubles with this particular line of disk, but before I upgraded to Leopard SD! was performing backups in less than 30 minutes and I haven't had any issues with the drive at all. Now its taking nearly double that. I'm experiencing copy rates of 9 mb/s all the way up to sometimes 22 mb/s whereas on Tiger it was much faster than this.

Any ideas as to what the problem may be? I put the backup folder on my external in spotlight's privacy list and that didn't speed it up any.

Thanks!

[edit]
An observation: the backup I just performed seemed to start out fast and gradually degrade as it moved from folder to folder. It started out at 22 mb/s when copying my users folder, but by the time it hit the Library and System folders it was down to 9mb/s. It just started on the Applications folder and its down to 8.5 mb/s. Interesting. Here's a section of the log:
