setKeys + array operators = slowdown

Subject: setKeys + array operators = slowdown

My Core Data project has about 300 records of data. The setKeys method + (void)setKeys:(NSArray *)keys triggerChangeNotificationsForDependentKey:(NSString *)dependentKey is used for approximately 10 dependent keys. A separate window uses array operators on the data. However, this combination seems to cause a massive slowdown on performance of the data calculated and displayed by the array operators. If I comment out the setKeys methods, the array operators calculate instantly. My question: is there a way to temporarily disable the setKeys method when the array operators first calculate on the 300 records? Or is there a better way to do this? Or am I missing something? Thanks! -Bill
