Title:
  Heavy Disk I/O harms desktop responsiveness

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: linux-source-2.6.22

  When compared with 2.6.15 in feisty, heavy disk I/O causes increased
  iowait times and affects desktop responsiveness in 2.6.22

  this appears to be a regression from 2.6.15 where iowait is much lower
  and desktop responsiveness is unaffected with the same I/O load

  Easy to reproduce with tracker - index the same set of files with
  2.6.15 kernel and 2.6.22 kernel and the difference in desktop
  responsiveness is massive

  I have not confirmed if a non-tracker process which does heavy disk
  i/o (especially writing) replicates this yet - will do further
  investigation soon
