Question

Answer 1

Turn off Background App Refresh in Settings General. Also, get rid of NSLog--they slow down beyond what it takes them to print.

I was able to reproduce the slow down effect on iPad under IOS7. In fact IOS6 did not have Background App Refresh.

I believe Apple aims for top of the line models, all others have to adjust.
