I got the entity from the context, fetching all objects & then

dramatic difference in performance?

That's a good resource that I've looked at, but my question is why
is there a difference in performance accomplishing the same lookup.
The article answers that question. The lookup is not the same. Try
"Analyzing Fetch Behavior with SQLite" (previous section the article).
