Why then do the impartial tests from Ars Technica show improvements for both devices?

I have installed 9.0 on a 5s and first gen iPad mini. I have not noticed any changes to speed/ app switching etc. After a bad experience with 8.0 and 8.1, I wasn't planning on updating for a few months but I really wanted the content blocker functionality (which turns out doesn't work on the first gen mini).
However I am not a power user; I just use web, email, FaceTime, simple games. I think it is useful if people mention how they use their devices in these threads as everyone seems to have differing experiences.

Safari seems snappier (no pun intended).
Metal enables higher benchmarks, O.K.
Real-world, everyday actions throughout the OS....significantly laggy
I'm sorry but you're incorrect. iPad 2 doesn't support ad-blocking at all as it's a 32bit device. Ad-blocking is only supported on 64bit devices (air and up, 5s and up).
I guess we all have different requirements, because I find iOS 8 nearly perfect on the iPhone 5 (bar some jitteriness), and there are quite a few iOS 8 features that I find essential, plus the security fixes.
Tonight I used the two 5C's and the 5C running iOS 7 was significantly more responsive. Like you say everyone has their own needs. For me, I refuse to add features if it sacrifices speed and I'm not worried the least about security issues on an iPhone.
Guys, do you think it could be linked to something like iCloud? I wonder if the people with smooth devices (no lag) are not using iCloud and maybe using Google or some other service?
Whenever I restore (even a clean restore) I enter my iCloud information. That's the only difference for me. It could explain why some devices see improvements and others degrade.

I feel like the memory management and/or footprint is better on 9 than 8. I'm experiencing far fewer reloads of apps.
its not that 32bit doesnt support it, its that apple chose to block access to content blockers for 32bit devices cause they feel there will be a large performance hit, which overall is probably a good idea. we already have the yearly squaking about "current crap slow stuttery ios", if apple thinks something will bog down a device, it probably will
theres supposed to be a way around it using xcode urself or something i saw on here, dont shoot the messenger

I have also done the same, and there is a slight difference in fluidity between the two, but yeah I'm the opposite, I am happy to make slight sacrifices in speed if it means security and features (Call and text forwarding are amongst my favourite feature ever added).
Yep, 64bit CPU can compare strings (which is what ad blockers do - compare crap on pages with blocker's database of crap) twice as fast as 32bit.
This is one possibility. I use iCloud only for contacts and calendars. No background backups, uploading photos and such.
Other possibilities: Caching. The new installation of 9 has the caches emptied. Takes a few days until they are full again. If you compare with a ios8 device, the latter will have a slight advantage.
But finally it is not important if an app starts a few milliseconds faster or if the device boots 2 seconds quicker. I also don't care about animations or transparencies.
Important is the usage quality of your main apps. In my case it is Safari and Feedly and a few others.
These run very well with our old ipad mini 1 and ipad 2. Of course the older devices are not as fast as new ones. But they are still quite capable and usable.
If you need speed for games, you will need to upgrade hardware of course.
So to conclude: iOS 9 is one of the best upgrades ever. It runs very well on new devices and sufficiently well on older ones. Perhaps the 9.1, 9.2 will be even a few percent faster, but iOS 9 is probably the maximum in speed you can get from your devices.

I may have missed this if it's been mentioned, but Ars has two articles specifically addressing the 4S and the iPad 2 with iOS 9, and a third article comparing 8 to 9 on various devices, including what I guess we'd call "legacy" hardware at this point (like A5 devices).
