I have an ipad2 and the ios9 is indeed giving this A5 a workout.. I had a lot of freezes, pop up ads (specially once you have visited the Drudge Report) Just have a look at your website data in the Safari advanced settings..Even by deleting the history the same nasty websites were setting cookies..I went to the private browsing mode and now I haven't seen any freezes, so far no nasty pop up ads, and the website data stays clean except those were you logged in ...Just sharing my experience....
