Thanks for the info,

Guess you mean just noticed http://bugs.debian.org/722898, sorry for
missing it before. Benchmarks with your changes look promising.

This makes three tightly related bug reports

* partman-auto-crypto#678015
  [Guided partitioning took 26 hours to complete erasure of encripted LVM
  volume]

  Never used guided partitioning, but if there is a cancel button during
  wipe some of the proposed warnings may apply.

* debian-installer#721360 
  [warn that blockdev-wipe can be very slow]

  Originally also about guided partitioning.

* partman-crypto#722898  
  [blockdev-wipe is too slow]

Fixes for speed and message wording are proposed in the bug you
mention. Time to reassign and merge?

Regards,
