Comment(by francois):

 My daily ''tahoe backup'' got a huge performance hit after the upgrade
 from 1.5.0 to trunk. This the result of a typical daily run on 1.5.0 (+ a
 few patches).

 {{{
  16 files uploaded (186918 reused), 67 directories created (26010 reused),
 0 problematic files skipped
  backup done, elapsed time: 1:03:32
 }}}

 This is the result of the first run after upgrade.

 {{{
  1056 files uploaded (201639 reused), 14107 directories created (19134
 reused)
  backup done, elapsed time: 9:46:20
 }}}

 I've just launched a second run to determine whether it's only a one-time
 penalty due to the upgrade or if it's another problem. If this behavior is
 normal, it's probably worth begin mentioned in the release notes.
