Tar is known to be slow as, well ... , slow as tar, when dealing with
directories containing many many entries.  Dump would be expected to
normally be faster than tar with a major limitation that incrementals
can only be done on whole file systems, not directory trees.

Tar's slowness is accentuated during amanda's estimate phase when it
may make 2 or 3 additional passes over the directory tree.  If you
can live with reduced accuracy of your estimates, and the DLE changes
aren't drastically different from day to day, consider the calcsize
or server estimate features that avoid using tar (or dump) during the
estimate phase.  They are WAY - WAY faster.
