If you've got such a large amount of data, it seems unlikely you'd want to be updating it all during calculations using getters and setters. Instead, you'd be presenting some sort of aggregate view of it in your UI; so you'd have one copy of the data and one copy of the aggregation. They'd both live in the same model, but the code which performs the aggregation would write its results using performSelectorOnMainThread:... 1) network receiver captures packets, updates TheModel, possibly invoking calculation action 2) calculation function does its stuff, updating TheModel 3) aggregation function (in controller) does its stuff, calling performSelectorOnMainThread:... to update TheModel 4) main thread executes update selector 5) updates trigger KVO of View objects Hamish _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
