Backup/Restore Important Questions

If a domain is packaged on one cPanel server that is EXACTLY the same as the one it's being restored on why does this always take forever:

Converting email to cPanel 5

and why does the maildir conversion still run if it's already in maildir format??

It takes minutes to restore an account that's just a few MB in size because of these two things.
