Cloning time difference

[chidiar]

1- Cloning my Internal HD with CCC is Soooo much faster than doing an identical copy with SuperDuper.
AND,
2- The final copy is much smaller 45GB (with SD) as opposed to 50GB (with CCC) which is closer to the actual size of my internal Drive.

Can anyone enlighten me on these 2 discrepancy?

Thank you

We're investigating #1 (see my most recent blog post). #2 is likely because we're skipping more temporary files, swap files, sleep images, etc... assuming you've used "Backup - all files".
