But not by much,
gnutar has to run the estimates 3 times
(level 0, current level, cunnrent level + 1).
with over 500G disk that's easy 6 hours

calcsize does all 3 estimates in one go,
is more than 2ce as fast per estimate then gtar.
Doing estimates on 600+G witch calcsize takes a bit less than 45 minutes
on a Sun UE450, the gtar stuff took well over 4 hours for just 2 levels
(level 0 and level 1, since current level was also level 0).
At that point I broke down, hacked the amanda source a bit and switched to
calcsize.

Or use calcsize ;)
