Title:
  update-motd-updates-available wastes 1 second on every login by
  forking hundreds of /usr/bin/stat

Status in “update-notifier” package in Ubuntu:
  Fix Released

Bug description:
  The /usr/lib/update-notifier/update-motd-updates-available script
  executed on console logins is painfully slow, taking almost a second
  to run.  Debugging reveals that this is because it forks /usr/bin/stat
  hundreds of times.

  The entire NEED_UPDATE_CHECK logic can be replaced with a single call
  to find -newer, which speeds up the script by a factor of 20.
