It turns out to be almost never the case that you want to fetch all "Open Tasks". It tends to be the case for us that you almost always want to have additional qualifiers on those searches, which ends up that you fault a HUGE (many thousands) of EO's in just to turn back around and filter them down in memory. Instead, I can remove that relationship completely and provide just the variant of the to-many that takes a qualifier.

Of course not and I agree 100%. But the example was user <- >>transactions which *I* would not fetch manually unless I had problems with multiple instances.


And the case above would normally be in an SEC which would have no outgoing relations anyway.

But I do recall you fixing that NSArray bug, now, and I actually haven't timed this out ... Might be interesting to see a graph of fault speed as that array size grows on a "normal" sized EO.

From what I remember not really much. Something like 600ms for 20k objects if memory serves.


Cheers, Anjo
