The same thing is happening in the App Store, with download speeds averaging around 256 kilobytes per second. I have tried changing the DNS to both Open DNS and Google Public DNS, and none of them seem to fix the problem. Again, I am having extremely slow download speeds only in Apple applications.
I recently purchased a Late 2013 Mac Mini Quad Core i7 2.6Ghz with 4gb DDR3 ram, 1TB 5400 rpm drive model APPLE HDD HTS541010A9E662 running OSX 10.8.2 I used Migration Assistant to migrate apps and files from Macbook Pro to Mac mini over gigabit Ethernet. The Macbook Pro is an early 2008 model equipped with a Core 2 Duo processor at 2.4Ghz with 4GB DDR2 Memory and an (upgraded) 750GB 7200 RPM hard drive model ST750LX003-1AC154 running OSX 10.7.5 Link to model: Why does my 2008 Macbook Pro completely outperform my Late 2012 Mac Mini when switching applications?
The Mac Mini outperforms the Macbook on all other fronts. I normally run Adobe Lightroom, Photoshop CS5, Adobe Bridge CS5, OpenOffice, and FireFox and I regularily switch between them all. Changing from Lightroom back to Firefox will bring up the beach ball for 15-30 seconds, and beachball again if I wish to open a new firefox tab. This doesn't happen on the Macbook. It is purely the hard drive RPM difference? 4GB of RAM isn't much to be running all of those heavyweight apps at the same time.
My guess would be that it's doing a lot of paging to disk. Check the size of the swap files on both machines. Go to the Finder's 'Go' menu and select 'Go to Folder'. Enter /private/var/vm/ into the box and press the 'OK' button.
Add up the sizes of the swap files. If it's more than 1GB I usually reboot.
That will clear out these files. I've seen these files up to 4GB on a machine with 8GB of RAM. Since running out of RAM can cause writes to disk, the difference in disk speed may be what's causing the delay. Either Finder or System UI server handles the application switching and I agree with you that this shouldn't be something the system needs to go to disk to generate. Let's break down the performance on each machine to be sure some other process isn't hung and if it's really IO or CPU or memory thrashing. Open two terminal windows on the old Mac.
You'll need to know a little about typing - and that these commands don't quit, so you click your mouse on a window and then press Control-C to quit these. Also, there will be a lot of data you don't need from these tools - so look at patterns and what changes rather than focusing on the absolute numbers:. iostat 1. vmstat 1 After about 20 seconds of both tools running, fire them up on the second Mac and adjust the windows so you can see all 4. When the Mac is just sitting there, you should have no disk writing, the CPU should be 90% idle or more and most 'page in' should be 0 with a few less than 5.
At this point you can poke the keyboard to pull up the app switcher. Watch for page in under vmstat and also keep track of how many apps are open. The most likely cause is the slow Mac has little Inactive RAM as well as a tiny slice of Free RAM. The tiny slice of Free RAM is by design - but you want your Wired plus Active RAM to be between 50% and 66% of total RAM to avoid delays. Let's stop there and see what your measurements show.
There are many questions here on what free, inactive and other types of RAM are. My hunch is the slow Mac is paging and has too many Apps open for the RAM equipped.
If you open Activity Monitor, you might see something like this under System Memory If you see that, quit a few apps until your RAM looks like this and repeat the timing of the app switcher test.
Each year, fall ushers in a few certainties. Leaves change color and fall gently to the ground. Flavors turn up in unlikely foodstuffs. And owners feel pretty sure that Apple has intentionally slowed down their smartphone, in a dastardly attempt to get them to upgrade to the latest model.
That last one? It’s not a thing. Hue and cry about Apple’s “planned obsolescence” has burbled up for years, at one point gracing even the pages of. But a new look at historic iPhone performance data disproves the notion for good. Does your iPhone run a little slower than it used to, just in time for the? If you’re blaming Apple, though, you’re barking up the wrong corporate monolith.
Update: Since this article was published, Apple has admitted it intentionally slowed down some iPhones to mitigate crashes caused by aging batteries. The company still wasn't doing this for the reasons many continued to suspect, which are outlined in this article. While everything in this report is still accurate, we urge you to also read what we now know about. 3DMarks the Spot The data that disproves any malicious intent on Apple’s part comes from Futuremark, the company behind a popular benchmarking app called 3DMark. The app runs a series of tests that measure your phone's performance. In fact, Futuremark’s data set includes hundreds of thousands of benchmarks for seven different iPhone models and three different versions of iOS.
You can see a bunch of charts, and they all show the same thing: GPU performance holds steady on an iPhone 5S, even across three firmware updates. The CPU wavers a skosh, but not enough that you’d notice. So, your iPhone’s GPU and CPU don’t shrink over time, and especially not at the specific time that iPhones start tumbling off the Foxconn assembly line. You can have faith in that both because of the rigorous Futuremark analysis, and because the planned obsolescence theory never made any sense in the first place. “The longevity of Apple’s devices is a key reason why their resale value is so high, which in turn is one reason why people keep buying them and handing them down to family members or selling them on when they get new ones,” says Jan Dawson, founder of Jackdaw Research. For more proof of Apple’s faith in its devices to keep chugging, note that it’ll sell you a brand new—or refurbished—iPhone 6S right now.
If it really downshifted devices after a couple of years, why on earth would it be selling you a two-year-old device? If you sell someone a rotten banana today, they’ll shop at the next fruit stand over tomorrow. (Yes, this metaphor assumes multiple competitive fruit stands in close proximity.) “I don’t believe for a minute that Apple deliberately slows down older phones or does anything else to prompt users to buy new ones,” says Dawson. If this still doesn’t compute, and you’re still suspicious because you know in your heart that your iPhone works more slowly than it did when you first bought it, you’re probably correct.

But why has nothing to do with Apple sabotage. Heavy Apps Your GPU and CPU still work as intended.
You’re asking them to do more. The operating system itself contributes to that load somewhat— demands more from your device than iOS 9 did—but Joki pins the majority of blame on apps that creep up in size and processing hunger with each passing year. Not every app does, but if your iPhone feels in need of an upper, you’ve likely got a few installed. Think of it like this: You own a station wagon, and each year you fill it with slightly bigger boxes. Eventually, the boxes don’t fit in your car anymore. But it doesn’t mean that Subaru has deviously shrunk all of its 2015 Outbacks. Surprisingly, Joki blames app bloat another common old-iPhone lament: battery life.
If your device doesn’t make it as late into the night (or more likely, afternoon) as it used to a year or two ago, that’s at least in part because more processor-intensive apps increase the strain on your battery. Older than that, and you may just have to face the reality that batteries don’t last forever. These issues aren’t unique to Apple.
If you think a 2015 iPhone doesn’t work so hot today, try, say, an Xperia Z5. In fact, older Android devices suffer more from a related but slightly different problem, which is that developers rarely manage to optimize for every device type, and older smartphones often don’t get operating system updates in the first place.
Freeze Frame So iPhones do slow down a bit over time, largely thanks to your various downloads. The natural question might be: Why doesn’t Apple do something to stop that from happening? Be grateful they don’t. And even beyond the business case, Apple has added some genuinely useful features over the last few years.
IOS 9 made Siri actually usable, and introduced “app thinning” to save space on your device. IOS 10 overhauled iMessage, Apple Music, and more. IOS 11 brings a new App Store, and FaceID for you iPhone X diehards. That’s in addition to countless under-the-hood improvements to improve the overall experience. It’s frustrating when an iPhone slows down, just like it is when leaves clog your gutters, or your pumpkin spice latte gets cold. And just like those other unfortunate side effects of fall, there’s no underlying conspiracy. It’s just how things work.
