Read my edit.

Seriously - you are lucky your eyes are not as sensitive as ours. You should just agree there are people like me, and many others, that can see the issues with iOS9 plain and clear. Please also realise that Apple improving iOS9 to satisfy us people who can notice these things will make YOUR experience better too.

You make it sound as if it's fine as it is, and that improving it further will someone be a bad thing...

I am telling you that at an objective level iOS9 is worse, pure facts and figures pulled right out of Xcode.

iOS9 never even caps out at 60fps scrolling, I'd typically see 50-55fps once it ramps up, but it would often start off as low as 15fps. I've no idea if this is Apple's smart move to reduce CPU usage (similar to Android's CPU governors), but it leaves much to be desired with regards to stutter - Android has similar issues with aggresive governors that use CPU stepping depending on how intense the usage it predicts will occur based on your actions.

I've also been to Apple Stores just to see whether or not it was just my phone (never been a believer than certain phones are magically laggier than others) - nope. Every single iPhone in the Apple Stores exhibits the same lags in the same areas.
Yes.My air 2 stutters each and every time in the App Switcher now without exception.i have like 4 games and 3 productivity softwares installed.It is impossible for any other Air 2 to run better than mine
As usual, even when I break it all down to the basics, what I say seems to get ignored and applied to exactly the things that I specifically point out that I'm not talking about. Unfortunately not surprising at this point at all.

I've literally no idea what you're talking about.

I'm telling you on an objective level iOS9 has lower FPS than iOS8... if you do not notice this then fine, but it is there whether you like it or not.

Ummmmm.... Huh?o_O
And what I'm saying is that while some might still have disagreements with that, most people don't question that there are stutters here and there. What a number of people do question though is the level to which various people that experience issues take them--some are experiencing worse issues than those and come off outraged that others aren't as upset about them even though others aren't experiencing them to the same degree or even at all (again, this is beyond the stutter in various places), and in other cases others are making a big deal about saying how this stutter in a few places makes their device completely unusable and that this is the worst iOS update ever, and follow that by going out of their way to tell people that they are blind or lying if they don't feel the same way, or that they are crazy if they haven't updated yet and are going to do it.

The extremes and absolutes that keep on coming up (not from everyone, but still often enough) are what's being questioned. Yet most of that time that is being applied as people just apologizing for Apple and just pretending there aren't any issues at all and saying that those who have issues are just making them up, which isn't happening at all (again, not in this context of what I'm describing). Basically in the eyes of many (not all, but still plenty) who have issues practically anyone who questions anything seems to be pigeonholed into the "denier"/"apologist" group simply for not just agreeing with everything, and that's just not how it is at all.

Okay. Think I have it.

Issue: Lag: True
Severity: Varies by user
Perception/Impact: Varies by user.

That's a somewhat simplistic way to look at it, but as a quick and short way to approach it, that's a pretty fair take on it.

I have found that performance is better than in the betas, but battery life is much worse than in the betas. iPhone 6 and iPad mini 1. (Could be this terrible Facebook bug draining my battery).

Edit: My phone seemed to heat up a lot today when I was using it for music only. The battery was draining at an alarming rate.

Everyone on same page now? Good.

Doesn't understand why it took 2 weeks to align everyone on basic—fundamental facts.
Because things outside of those facts were often brought up and when those particular things were questioned it for some reason was treated as if the underlying facts (and not the things beyond and outside of them) were being challenged and questioned instead. Anyway, seems like things have gotten aligned better at this point, as you mentioned, which is good.

Sarcasm solution: reduce transparency/ motion.

Real solution: wait.

Profit solution: sell device.
Well, might not be as much of a sarcasm solution (or a workaround at least) for those that might fare better with reduced/different animations (as well as those who don't really are for animations anyway).

Just updated iPad 3 to iOS 9.1 from 8.4.1.

Perform admirably slow on every area, expect safari (way smoother now). Well, I can still revert back to 8.4.1 (OdysseusOTA 2). Let's see how it develop for few days then.

Until 9.1 has a jailbreak, I don't think you will be able to go back to 8.4.1 using OdysseusOTA 2

Wish I could have an FPS counter. What's the average FPS in app switcher for A7 iPads? :) particularly entering/exiting the switcher

I don't have a Mac thus I don't have Xcode so I can't figure it out myself, I'm just generally curious because the app switcher in iOS 9 is quite possibly the laggiest thing I've ever seen on iOS (besides the blurred safari favorites screen plus split keyboard plus control center on iOS 8 and later)

What I don't get is why has the performance reduced on Air 2 whan absolutely nothing has changed in the interface......
This is actually a laughable story because performance is the main thing noted on "what's new in iOS 9"

Battery life is slightly worse on 9.1 but not really noticeable if no percentage showing and should not prevent anyone from upgrading.

I'm very happy with the battery life on my iPhone 6S+ with iOS 9.1...
it's better than my previous iPhone 6+ even through 6+ have a larger battery than the 6S+
