I understand that portal filters have been optimized a while ago for better performance in FM12. However, when I briefly asked about this at the FileMaker tech booth at Devcon, nobody could answer the question.

Searching other threads here provided some information; but it was not especially complete or authoritative.

 

I also briefly tried a knowledge base search. Again, no luck.

Is there some kind of clear definitive statement on this subject?

Yes, I am talking about portal filters, the calc option that you define in portal setup; NOT in the relationship graph.

 

Apparently Matt Odell spoke on this subject at some time.

 

Supposedly under certain circumstance, a portal filter calc provide the rough (or exact?) equivalent of what you can do in the graph.
