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.
