I’ve just had a dig about and this looks to have been raised in June last year here: Sluggish Performance. Large Collection - #20 by paultaylor
@paultaylor should I follow the same advice as you gave in the thread linked to above?
I have to say that I don’t think that this is the root cause of the issue I am trying to resolve but I have perhaps inadvertently introduced a secondary issue that can be fixed fairly easily. Let’s see what Paul says.
Cheers,
