Can this be easily verified I wonder? It'll be easy to verify by taking a packet capture. PSN is due to collapse. Its not built for the future. Cant even change your name or region on it. Only a matter of time, and they thought that hack a few years ago was bad.
Interesting article! My friends and I do not only have the slow download problem, but something even worse: The "preparing download" takes over minutes times, often even longer than the download itself especially when loading updates for installed games. Did this issue ever occur to any of you guys? I really wonder if there is a fix for this. Interesting Article. However, there must be other reasons for slow speeds.
Otherwise, pausing and resuming a download should not help, which it often does. Sometimes dramatically so. Impressive analysis, thank you for sharing. I noticed on your graphs you were testing in the late morning, did you see a variability throughout the day? My reason for asking is that in the US, netflix would often be the worst from to , I'm curious if you matched that pattern. That might indicate an overall network load correlation.
The PS4 has a special chip that can download files while the rest of the PS4 sleeps, right? Probably some integration with that that's causing it.. This was covered in an earlier comment.
Downloads being handled by a coprocoessor was the original plan, but that's not what Sony implemented. Even in rest mode, it's done by the main CPU. My belief is that they've done this intentionally to prevent performance issues from downloading quickly, probably with a big issue being disk access from downloading so fast, as well as affecting latency for online games and CPU usage.
While using a local proxy is a good workaround the PS4 at least the original model can be almost unusable while downloading especially multiple downloads , causing both the games and OS to stutter and the controller to become unresponsive, taking 3 or 4 seconds to react to a button press.
Sure, it could be that this is what they were going for. The static limit on the receive window means that your setup still ends up unusable due to the downloads being too fast, while other people have their downloads unnecessarily throttled to a speed far below the effective disk speed.
Without it, downloads would take hours, with it, minutes. Is it possible the latest system software 5. Can't say for sure without actually redoing the testing. Download speeds can vary for all kinds of reasons; the only way to be certain are systematic tests.
But my feeling is that they haven't fixed it. At least I had an awkwardly slow download last week, after having forgotten to close a game. But it could also have been just a coincidence. It all depends on your Internet connection. I live in the middle of nowhere and get 1Mbps. I can just about stream SD video as long as nothing else is using the connection, and so I applaud anything Sony are doing to throttle downloads when anything else is using the Internet connection.
The problem here is that the Youtube or Netflix app is on is an awful way to detect whether somebody else is using the connection. First, it has false positives due to including the cases where the app is actually active or not.
If Youtube is suspended in the background, there's absolutely no way. Second, it has a ton of false negatives due to only looking at what's happening on that PS4 system.
That's an absurd assumption: in the modern world a household will have half a dozen devices using the same internet connection. The current solution does not help at all for the case where I'm trying to watch a Youtube clip on my computer while the PS4 downloads something, or someone is trying to read a webpage on their phone, etc.
Like I wrote in the post, there are proper ways of doing this by looking at the actual network traffic patterns. The "what apps are kind of running" approach chosen for the PS4 is just totally broken.
I don't know if it's just me but my Playstation 4 has had absolutely terrible internet speeds. Nothing I've done has worked, and this has been a problem since the latest firmware update. Had zero problems, downloads started immediately and were consistent until they were finished. On the Playstation 4 the speeds fluctuate all over the place, sometimes it changes dramatically when I pause and resume.
Then it slows down more and more until it becomes unbearable. Then there's the questionable sign in problem along with PSN overall being medicore in the past few months. So how does an old, 12 year old console from the past generation give me better speeds and better consistency than a modern console that is supposed to be good?
It's very frustrating. I'm this close to buying a new Slim PS4 model just to see if the download speeds and performance are any better. Could please Test the slim version? I would like too see what has actually changed or improved on the Slim model. I am having very slow downloads speed on my PS4 that has wired connection to the router and nothing running in the background.
Why have we gone from buying decent full games that download fast on ps3 to broken half a games and really slow downloading. I am going off gaming completely just because if I want to buy and download a game I have to expect to play it the next day after I originally wanted to play it and then I just go off wanting to play the game.
Was trying to download expansion packs for modern warfare was going to take 16 hours for 16GB install. Closed all my apps running I forgot to close including Modern Warfare and Netflix As an antispam measure, you need to write a super-secret password below. Today's password is "xyzzy" without the quotes. Why PS4 downloads are so slow. Posted on in Networking , Games. Background Before running any experiments, it's good to have a mental model of how the thing we're testing works, and where the problems might be.
Maybe the client doesn't support the TCP window scaling option, while the proxy does. Without window scaling, the receive window will be limited to 64kB. But since we know Sony started with a TCP stack that supports window scaling, they would have had to go out of their way to disable it. Slow downloads, for no benefit. Maybe the actual downloader application is very slow. The operating system is supposed to have a certain amount of buffer space available for each connection.
If the network is delivering data to the OS faster than the application is reading it, the buffer will start to fill up, and the OS will reduce the receive window as a form of back-pressure.
But this can't be the reason; if the application is the bottleneck, it'll be a bottleneck with or without the proxy. The operating system is trying to dynamically scale the receive window to match the actual network conditions, but something is going wrong. This would be interesting, so it's what we're hoping to find.
The initial theories are in place, let's get digging. When the download was started, the game Styx: Shards of Darkness was running in the background just idling in the title screen. The download was limited by a receive window of under 7kB.
This is an incredibly low value; it's basically going to cause the downloads to take times longer than they should. And this was not a coincidence, whenever that game was running, the receive window would be that low. How to Speed up PS4 Downloads? Tip: If your PS4 runs slowly, what should you do?

But that doesn't excuse the limitations enforced by secondary apps like Netflix, he argues. And since they can keep running with the user unaware, here you have the problem. That is as close to a layman's explanation as I can make of some very intricate networking terms and concepts.
I recommend reading the whole thing for yourself to get a better understanding. It makes no guarantees that it has the answers, but at least you'll come away from it knowing that you aren't crazy: PS4 download times do suck.
