Not sure why but for the same library, the batch analysis of tracks when run in the Iphone version (on Iphone 5) takes much less time than the Ipad version (on IPad mini and iPad 2). I also noticed you issued an update for the iPhone version but I didn’t see the same for iPad. Is this the reason? Can you issue an update for the Ipad version to shorten the time?
The iPhone 5 uses a faster A6 processor, while the iPad mini and iPad 2 both have a slower A5 processor, so this would be expected.
