I have just performed some full backups on a host after disabling compression.  Results:

Not-first backup with compression:  139.9 minutes for 70000.6 MB
First backup without compression:  76.7 minutes for 70181.5 MB.
Second backup without compression:  36.6 minutes for 70187.4 MB.

Wow:  Four times the performance.  Looks like compression is a *significant* performance-eater.
