[Tracker] trackerd's disk access slows down system

[Tassilo Horn <tassilo member fsf org>]

Hi all,

I use tracker (0.6.1) on my laptop system and I really like it.  But one
thing that annoys me sometimes is that tracker can slow down my system
considerably if there are a lot of files that need indexing.

For example I like it to index the source code of some projects I'm
involved, where a huge part of it is auto-generated from some schema
definitions.  So whenever the generator ran about 1000 files have to be
indexed anew.

Till that is done I hardly can start applications or do other stuff that
needs disk access.

Is it possible to tell trackerd to always let other applications have
precedence in disk access?  Or would another IO scheduler attenuate my
problems a bit?  Currently I use the CFQ scheduler.

I think that would be a very useful feature for anyone with a system
where the slow disk is the bottleneck.  I think that's the case for
nearly every notebook.

Thanks in advance,
Tassilo
