Beta 2 runs a lot better than the previous Beta 1. I am using an iPad mini and while it is still relatively slow, it is now at least usable again. There is a huge difference between beta 1 and beta 2.Beta 2 now runs faster than 8.3 did, as far as I can tell. I hope they optimize it even more, but even if they don’t it’s still an improvement. don’t expect miracles, thought.
