This issue is not getting enough attention. I don't know if you all have SSDs but most people don't. On hard disk drives this is a huge issue. System responsiveness drops when tracker is running and pretty much nothing else can run smoothly while it's running, even on computers with fast CPU/large amounts of RAM. The I/O is often the cause of system slowdown and this needs to be reduced as much as possible.
I'm sure this issue can be fixed, a background daemon doesn't need to run at full speed, it can be niced to 19, and internal fixes can be made.

Title:
  Heavy Disk I/O harms desktop responsiveness

Status in The Linux Kernel:
  Fix Released
Status in The Linux Mint Distribution:
  Invalid
Status in linux package in Ubuntu:
  Confirmed

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
