Those are part of the GObject type system, and are used for type checks.
If you build without the glib debug type checking enabled, those should
get cut back a lot.

But that is kind of fixing the symptom instead of fixing the real
problem. Libmrproject is not optimized at all yet, since all
functionality is not added and we haven't done profiling etc. The real
solution is to not keep rescheduling as soon as something is done,
especially when loading a file or other "batch" type operations, where a
single rescheduling would be enough after the operation is done.

Other than that, there are a lot of small optimizations that can be done
I'm sure, but I don't think they would matter much once the above is
fixed.

That sounds like a lot, it sounds like a bug. Is it a huge file? If you
send me a test case, maybe I can take a look.
