I don't have a 6s plus (maybe later this month) but I think some people exaggerate about the performance of the 6+. Maybe its because I didn't try the new 6s yet, but my phone is perfectly fine for everyday use and i'm a power user. It doesn't lag or it did not feel slow at all (that's why I dont know yet if I will upgrade).My old iPad 4 lag and its slow now, but not my 6+, at all. In fact iOS9 help some issues I had with iOS 8. Safari tabs didn't reload as much as before as well as apps, and the refresh problem when you actualy are on the same webpage is completly gone for me.

iPhone 6S actually that much faster?

I plan to upgrade soon, so I'm sure I'll notice quick a nice bump in speed. Then again, I'll be going from a 4S to a 6s. 
in this forums people exaggerate about everything.
I still have to see an iPhone (>5) that has real performance issues.
On this forum people just speak about lag and stuttering. In the real world my wife doesn't even know what is the meaning of "lag" using an iPhone ...
People here are describing the iPhone 6S compared to the iPhone 6 like the 6 was a 5 years old smartphone.
Give me a break.
You don't have to convince us about your purchase.
Im happy to upgrade iPhone every year even if performance gain is minimal.
My biggest tell tale sign of the speed increase/RAM boost is the third party keyboards. Where there would be just a very marginal amount of lag on my 6 and Mini 3, there is absolutely none on my 6s and Air 2. This and Safari page loading and scrolling. Those two things make a huge difference in my experiences.
An iPhone 5 running iOS 6 could outpace all others.
A 386 PC running MS-DOS might be able to outpace a Core I7 running Windows 10. So what's your point?
Absolutely. I upgrade every year and I'll never learn my lesson that in *most* cases the S renditions are the worthiest of upgrading to me, this is solely my opinion. I find even with the new form factor of the numbered upgrades my excitement is always much more prevalent in the S upgrades.
I can't speak on the 6 to 6S but the 6+ to 6S+ is much faster and very noticeable.
On the 6 Plus I would routinely experience constant Safari tab reloads, App refreshing when alternating between more than 3 apps (very annoying when you lose your GPS routing because the thing has to refresh), phone totally locking up and not responding to touch for a good 5-10 seconds, etc. The only iPhone I've ever owned that had performance issues (by iPhone standards) right out of the box.
On the 6S Plus absolutely everything is smooth. Apps and webpages can be held in memory. Multitasking is enjoyable and works properly like it was meant to. The 6+ is probably the iPad 3 of iPhones and the 6S Plus corrects all of its glaring deficiencies.
For those who were fine with the performance on the 6+, the 6S difference probably isn't as noticeable.

The difference in speed between 6 and 6S is small but noticeable. Check out this video comparing web browser speeds.
Will the speed between the 6 and the 6s be noticeable for someone that is only a light user, i don't multi task, i just check emails and use the odd sports betting app and use runkeeper.com. I would rather buy the 6 for two reasons, the first being it is lighter, only 14 grammes but it is noticeable, i like my phone as light as possible when out running, and secondly it will be cheaper.
When i was playing with the 6s in store yesterday, it was loading the pages exactly the same as the 6 does in that video, which is also the same as my 5s does.
No, it won't be noticeable at all...
No matter what some people keep saying here, they speak about performance and then make examples speaking about page reloads (something that hasn't anything to do with performance but just with the more RAM available).
On single task operations (mail, gaming, messaging) or light web browsing (2-3 tabs) you won't notice any difference.
All that "power" wasted on a device/OS that can only have one app open at a time...wake me up when the iPhone finally gets at least some form of multi-tasking because until then, you can't even try to say the 6S offers "desktop class performance"
Sure, apps refresh less, whoopdidoo, but that increased RAM is a waste if you can't have 2 apps open at once.

Those videos, like most of the YouTube "scientific comparisons " , are just ridiculous.
First, the two phones are on the same wifi network, so if you know the basics of networking, it's impossible to open the same page AT THE SAME TIME on both devices.
Second, to open up a ridiculous amount of web pages and switch between them only means that IN THAT ASPECT, having 2 Gb is better than 1. Do you need a test for that ?
Click bait.
Nothing more.
In this very moment I'm using two apps, mail and safari, on my iPad Air. And it's a 1 Gb device....
So many people are missing the point here. It's not about keeping a billion browser tabs open, it's about keeping sufficient apps & tabs in memory. The 6S+ is faster in every way, be it navigating menus, scrolling, or loading webpages. It also keeps plenty of apps & tabs in memory, plus it has zero lag. The phone is noticeably better in practically every way. This is no incremental upgrade like a 5S over an i5.
It's a huge upgrade and if people don't acknowledge it then they will never be satisfied with iPhones because this is as big a jump in performance as ever happens.

Thanks for your opinion. However, this guy's opinion is different and many reviews have commented that the performance increase is marginal:
http://www.theguardian.com/technology/2015/oct/02/iphone-6s-plus-review-barely-better
I'll have to use one myself before establishing my own opinion.
@OP, The additional RAM alone makes a difference, I think.
if you are talking about anecdotally, as that reviewer was, then I would agree the speed increases are probably incremental; there isn't a huge difference between certain tasks such as swiping left and right on the menus to go between app pages....even the 4s is smooth with swiping left and right or launching the multi-tasker. Launching most apps won't be a night and day difference to the average user on an 6s vs 6/5s.
But if you're a power user, and you're looking for multitasking and work productivity, the 6S will step out of the crowd from the older phones as the extra ram makes for a night/day difference in multitasking and the chip itself is much faster than prior generations. Further, it will likely will be better future proofed than older iPhones have been thus far, and they've been supported pretty well - look at the 4S receiving a respectable update in iOS 9 and it runs fine provided you're not a power user. If it had 1GB of RAM, it would likely run respectably
All depends on your needs. If all you really do is text and make calls, send emails, use google maps and surf the web indiscriminately, then its likely not worth the upgrade from the 6 (unless other features attract you such as 3d touch) or from the 5s (unless you want a larger screen)...perhaps not even worth the upgrade from a 5/5c or 4s if they're meeting your needs.
In terms of raw specs though, the 6S is much more powerful than the previous generation of iPhones.

There are plenty of people on this very forum complaining about lags on iPhones be 6S ...
On MacRumors when I read the word "lag" I just stop reading, because I know that I'll find whiners.
I tried the iPhone 6S and compared with my 6 using Word, Excel, Mail, Safari and Real Racing 3.
Differences in real world usage ? Very few if any.
Surely it can handles more tabs on Safari and generally speaking it handles better multitasking (within the limits imposed by iOS implementation).
But it's not night and day like many of us, to justify your purchase, are writing here.
It's an incremental upgrade, as usual.
I'm an Apple enthusiast user, thus I'll probably buy it in a couple of months, but I don't need to exaggerate on the forum like many are doing here.
I would be the last person to exaggerate praise towards Apple. If a previous 6+ owner doesn't consider the 6S+ to be a monumental, not incremental, upgrade then I would wager that they only really use their phones in a very basic manner. To fail to see the many shortcomings of the 6+ says it all really. If you don't notice how bad one product is, how would you notice how much better another is? Unless you're a multitasker and major browsing nut then I would imagine that the jump from i6 to 6S may feel incremental but for us 6+ owners the 6S+ has been a revelation.
It is incremental, doesn't matter how much you try to twist it...
6S+ is a great product, like the 6+ that was a great product too.
They sold millions and millions, and they are still sell it.
How though?
Anecdotally? Sure
My 4S runs iOS 9 mostly fine too, and swiping left and right on the home screen isn't noticeably different from my 6s for example
Actual tech specs?
Not at all. Its not him "twisting" it; 2GB of RAM is very different than 1GB, and the benchmarks don't lie as to how powerful the A9 is over the A8. Its a huge difference.
