So I finally got to read for about an hour and a half yesterday (stupid addictive forum!), with 2.1.1. Page turns are nice and fast again, BUT, I had loads and loads of dead taps. Also unresponsive swipes. After about an hour of reading, almost every page gave me no response at first try to turn it... I had to try a second time and sometimes even a third time
I tried different areas of the screen and different swipe and tap techniques...
