I should add. I tested with the new throttle code in the daemon & the
ioprio added too and changed the value of the throttle in my tracker.cfg.

By default it is 0. This means NO throttling occurs. On my machine this
is ok unless I am doing something else which needs a lot of power.

I tried running with the throttle at 20 (maximum) and instead of finding
all my files in about 10-15 seconds and using 50-100% CPU, it used < 15%
the whole time and these are the results:

 Tracker-Message: Total time taken : 348.7701 seconds
 Tracker-Message: Total directories: 7100 (4917 ignored)
 Tracker-Message: Total files      : 158866 (23950 ignored)
 Tracker-Message: Total monitors   : 7100

The indexer also makes use of the throttle. Instead of saying it would
be done in 3hrs, it guessed at 21hrs. But you wouldn't even know it was
running.

Using the throttle is certainly the way to go here I think. Jamie do you
think setting the throttle to 5 or some value just above 0 is a good
idea? We use 5 for laptops running on battery at the moment of course.
It might make sense to push that to 10 and use 5 by default. People are
definitely going to notice their machine's usability dropping before
they notice the time it takes to index all content being too slow.

Thoughts?
