I just dinked around until I found something that worked for my app (which can create many more ops than there are cores). I ended up with: const NSUInteger numCores = [[NSProcessInfo processInfo] processorCount] * 2 - 1; [self.searchQueue setMaxConcurrentOperationCount:(NSInteger)numCores]; -- Steve Mills Drummer, Mac geek _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
