And Snellman posits that there are legitimate reasons for limiting the receive window. 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.

Why are PlayStation 4 download speeds terrible? Here are some ideas. New, 76 comments. By Owen S. You need to seek help from a specialist in order to fix it for you. Take your PS4 to a repair shop managed by an experienced technician. When the data stored in the CMOS memory chip gets corrupted for any reason, one of the symptoms of that is the slowness of PS4. After reading this article to this point, you may have already figured out the 3 common solutions for this situation.
They are:. In case you need more elaboration, please do your own research online. The Rebuild Database option does a defragment of the PS4, which can solve a whole host of issues on the PS4 and free up some much needed space, speed up your console and fix issues.
The Rebuild scans the drive and creates a new database of all content, thus cleaning the disc drive. This will make PS4 run faster and resolve performance issues.
In many cases, when PS4 is lagging, doing this operation fixes it. Now, as to the specific steps for initiating a database rebuild, those are as follows:. If you own a gadget for a long time, you should factory-reset it every once in a while. Useless files accumulate, caches fill up with junk data and programs you never use start eating up valuable space. Video game consoles are no exception, particularly since games are larger than ever and hard drive space is at a premium.
You need first to go to Safe Mode that offers you a Quick or Full initialization. Either way, pick your reset style and confirm your choice. Then, get ready to re-download all your favorite titles and apps, and restore your saved data.
So, if you want to format PS4 internal hard drive, follow the steps below. Note that these steps are for Microsoft Windows OS. Once finished, connect the hard drive to PS4 again and perform a complete system software installation. Therefore, make sure to download the PS4 system software installation package on an external storage device USB flash drive is recommended.
This method often needs savvy to implement. But if you are a beginner, you must be careful in following the instructions. There are several reasons that make PS4 slow and lagging. Some are easy to fix and others, in rare cases, need an expert. But if PS4 lag still persists after trying everything in this article, contact a technician. There are several reasons that make PS4 become slow and lagging, such as corrupted system files, malfunctioning USB device connected, or a defective hard drive.
The answer is definitely YES. Dust hinders the proper CPU cooling which makes it consequently hotter, and this results in lower performance of PS4. Fixing the slow PS4 is not a difficult task. You have to follow the instructions in this guide in order to fully resolve this issue. Tags: ps4 lag slow ps4.
Or is that the same thing. Do you have any issue with other internet activities on PS4, such as downloading games, watching movies on youtube and so on? This is usually caused by bad sectors. This will restore the performance of the external HDD and eliminate these bad sectors. So that they will show per game as they do now?
If you back them up first of course. Both must be saved on the SAME device using that utility. Mine was unusable it was so slow even trying to shut it down through the menus was a task. The over heating can cause the GPU thermal paste to dry out resulting in further slow down.
Very easy to diagnose. If your fan ramps up to full speed when playing a game from cold, this is most likely your issue. Thanks for this nice addition.
Probably the PS4 is overheating and you need to clean the inside of your console. My ps4 used to work so beautifully.. And it was so very laggy. Please help. The PS4 internal hard drive needs maintenance. Apparently it suffers from bad sectors.
Please try to full-format it in order to restore its original perfromance. Most probably the PS4 hard drive is corrupted. You have to FULL format it in order to revive it. I just recently got gta v and while playing for about 15 minutes, the game crashed and turned off the ps4 by itself. I tried everything.
I deleted and downloaded it again, but I feel like it just made it worse. My PS4 just became slower and would crash constantly. Everything used to work perfectly fine until i downloaded gta. Apparently you have to replace the PS4 internal hard drive in order to work around this issue. Most probably you have a failing PS4 hard drive.
The main PS4 screen and other games work fine and respond as soon as i press or move a button. You have to connect your PS4 hard drive to a PC and perform a full format on it.
Please read this guide for more details. I have rebuilt the data base and reinitialized the whole ps4 and still nothing ive cleaned the ps4 inside entirely and it is still laggy but still runs some games for a bit then crashes. Is it the harddrive or something far worse?
It is suffering from bad sectors that causes it to slow down. Try first to connect it to a PC and full format it , then check again. Hello, Sorry if this is the 2nd time I post similar message. Could still try to initialize it aswell. Thanks in advance. Thanks for the advice! Great to see people like u still put time into great guide! Your problem is not so critical and is easy to fix with no cost. Please provide us with your update on your issue so that other users who have the same problem may benefit.
Recently Ive noticed that whenever I do anything on my ps4 it stutters while watching a show or going through ps4 menu it will stutter back on a input and the background flow with the themes are also stuttering. It is a old ps4 back from December and this started happening 2 days ago. Most probably your PS4 hard drive is declining. You better do a FULL format on it in order to restore the original performance.
My PlayStation system has a please wait message when I turn it on and after an hour of waiting for it to load it goes into a blue screen and stays there until it automatically turns off and the process repeats itself. I have not been able to play for 4 days now and I am not sure how to fix this. You might have an overheating issue with the PS4. Try to clean the inside of PS4. Or maybe it is a critical PS4 hard drive failure.
My roommate downloaded games onto my PS4 and filled up the hard drive almost all the way. After he did this, the PS4 was really laggy so I freed up almost half the space on the hard drive. 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. Having an app running e. Netflix, Spotify limited the receive window to kB, for about a 5x reduction in potential download speed.
Moving apps, games, or the download window to the foreground or background didn't have any effect on the receive window. Launching some other games Horizon: Zero Dawn, Uncharted 4, Dreadnought seemed to have the same effect as running an app. Playing an online match in a networked game Dreadnought caused the receive window to be artificially limited to 7kB.
Playing around in a non-networked game Horizon: Zero Dawn had a very inconsistent effect on the receive window, with the effect seemingly depending on the intensity of gameplay. This looks like a genuine resource restriction download process getting variable amounts of CPU , rather than an artificial limit. I ran a speedtest at a time when downloads were limited to 7kB receive window.
It got a decent receive window of over kB; the conclusion is that the artificial receive window limit appears to only apply to PSN downloads. Putting the PS4 into rest mode had no effect.
Built-in features of the PS4 UI, like the web browser, do not count as apps. When a game was started causing the previously running game to be stopped automatically , the receive window could increase to kB for a very brief period of time. Basically it appears that the receive window gets unclamped when the old game stops, and then clamped again a few seconds later when the new game actually starts up.
Conclusions If any applications are running, the PS4 appears to change the settings for PSN store downloads, artificially restricting their speed. There are a few important details: Just leaving the other applications running in the background will not help.
The exact same limit is applied whether the download progress bar is in the foreground or not. Putting the PS4 into rest mode might or might not help, depending on your system settings. The artificial limit applies only to the PSN store downloads. It does not affect e. This is why the speedtest might report much higher speeds than the actual downloads, even though both are delivered from the same CDN servers.
Not all applications are equal; most of them will cause the connections to slow down by up to a factor of 5. Some games will cause a difference of about a factor of Some games will start off with the factor of 5, and then migrate to the factor of once you leave the start menu and start playing.
The above limits are artificial. In addition to that, actively playing a game can cause game downloads to slow down. This appears to be due to a genuine lack of CPU resources with the game understandably having top priority.
Speculation Those were the facts as I see them. Q: Is this an intentional feature? If so, what its purpose? Q: Is this feature implemented well? Oh dear God, no. It's hard to believe just how sloppy this implementation is. Q: How can this still be a problem, 4 years after launch? Footnotes [ 1 ] How idle?

Previous « The mystery of the hanging S3 downloads. Thank you for investigating this issue. I was wondering about this for years now. Just thought it would be interesting. I don't think that's going to work : Large companies don't really have mechanisms in place for feedback like this.
The actual graphing was done with R, using the ggplot2 library. Any chance you want to assess the PlayStation Store website store.
