Umm. People give opinions in threads endlessly. Most of what is written on MR in myriad of topics is opinions. Aside from some of the ars technica articles, which was dismissed about ios 9 showing some performance gains, the focus has been on press an icon and measure the speed to which it opens. I use the ars article as some "proof" that ios 9 does indeed have performance improvements within and while there is some stutter in odd places..like the control panel in siri; it's only trolling because you decided to call it that. I really avoid this type of thing in the forum and it's clearly against the rules, but you seem to be doing what you are rallying against.
