[Bug 947664] Re: Unpacking linux-headers unbelievably slow in Lubuntu Precise (Beta 1)

[Brian J. Murrell]

The filesystem being used here is, no surprise, ext3.  I really don't
think this is a particular filesystem problem.

I'm currently testing dpkg's --force-unsafe-io.  I expect it will speed
things up, yes.  But what if it does?  Will Ubuntu actually use it in
it's package managers given that it's unsafe across power outages?  If
not, there's really no point in even testing it, right?

Title:
  Unpacking linux-headers unbelievably slow in Lubuntu Precise (Beta 1)

Status in “dpkg” package in Ubuntu:
  Incomplete

Bug description:
  The below is an example line in an apt-get dist-upgrade which seems to
  take 30 minutes or more on a 2.1GHz CPU (one core of a quad core
  through Virtualbox). I've been looking at it for ages, and even had
  time to log in here and file the bug  - the line is still 'hung'.

  Unpacking linux-headers-3.2.0-18 (from .../linux-
  headers-3.2.0-18_3.2.0-18.28_all.deb)

  Can anyone explain this, or is it a bug in the configuration of
  Lubuntu, Apt-get or something. I read that there was a similarly
  behaving bug to do with dpkg using paranoid file synchronization but
  this length of delay is frankly a bit crazy.
