Wow, factory reset did make a big difference in the speed. Now it’s back to about as fast as it was under KitKat — that is, it feels very laggy compared to my beloved Sony Z2 tablet, but it’s now tolerable instead of throw-it-against-the-wall slow.

I upgraded my 2012 Nexus 7 to Lollipop and it is s-l-o-w. I mean, really really slow. 9 seconds for the home button to return me to the home screen. 7 seconds for screen rotation to occur after I physically rotate the device. 6 seconds to open Chrome. This device was already slow before, but Lollipop (or some glitch triggered by the Lollipop update) made it dramatically worse.
