We have an application that keeps an array of bibliographic references, where each is an NSMutableDictionary with other properties. The largest file I recall throwing at it is ~20K items, and the main problem at that point was a beachball when using SearchKit...which was a nuisance to work around. It doesn't use bindings, but there really aren't any lazy loading tricks either.Well ... 20k items with only a couple of columns or 20k items with "many" columns. That one little detail makes all the difference. :-)
Good point. 8--10 displayed in the table (typically), but each item has an arbitrary number of values (typically < 20, though). Users can also display an arbitrary number of columns, so there are lots of fun performance problems to find :).
