Duplication speed KB/sec
- 10 years ago
You can actual see what speed duplicate are running at - indirectly.
The detailed part of the activity monitor will have a text like this:

And the writing of different backup images will vary in speed. Small images will show a lower speed than big images. Use it as a guideline
