Hi Jose

Lars will probably remember better.. but I think in 2.22 we had preheating
where all the object were loading in before the import started, so the
lookups would be very quick (but require more memory)

In later versions I think it now will try and "switch" over automagically..
but I don't think it then preloades all your references (just caching after
the cache miss threshold is reached), so if you have 42k org units... that
might be very slow
