[Bug 332790] Re: updatedb.mlocate slows applications to unusable state, while running

[Keith Hughitt]

Confirmed on 10.10 server. System runs on ext4 but there is also a multi-terabyte XFS storage partition which is likely the cause.
I have the updatedb in cron.daily, but no find cronjob.

Title:
  updatedb.mlocate slows applications to unusable state, while running

Status in “findutils” package in Ubuntu:
  Fix Released
Status in “mlocate” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: mlocate

  Every time updatedb.mlocate is running its scheduled task, it occupies hard disk and its bandwith
  so user space aplications become slow and unresponsive.

  Every time it runs i am mostly unable to do normal work on my machine an i need to wait
  couple of minutes, doing nothing until that updatedb.mlocate thing is done.

  I think that this is user-unfriendly behavior of updatedb.mlocate and I think that 
  it should run with some kind of lower priority to dissk, not disturbing user experience
  and nor destroying Ubuntu usability for those few minutes.
  I even switched time when that update runs , according to irc channel support,
  and it still bugs me and destroy usability when i use computer at that time.

  Current behavior: updatedb.mlocate occupies whole disk bandwith when it is run on scheduled time,
   not allowing user space applications to run and turn system in unusable state during that run.
  Crucial user-space actions are affected during its run.

  Wated behavior: updatedb.mlocate should run at lower priority at disk usage to avoid
  blocking Ubuntu computer for the time it runs.

  I run Xubuntu Hardy amd64 8.04.2/LTS
