Thanks Mike, I just looked with Instruments and well yes to process the data my app uses NSScanner a lot to extract date/time with its corresponding data values, so this takes about 99,6% Running-Time (gasp! )…
One error (I think) was that I processed the data inside the readFromURL:ofType:error: after it was read into the NSString….but: Now I pass the NSString fileContent from NSDocument makeWindowControllers to a new object WindowController: It doesn't change anything however, the corresponding WindowController which processes now the data is also taking a lot of CPU-time… Should I put the data processing in a dispatch_sync queue in the WindowController or in NSDocument's makeWindowController ?
