See here for an article how to do this for some popular routers. This is another very common reason why PS4 downloads can go slower than expected — there are simply a lot of people using the internet at the same time in the home and more generally , and this can increase network congestion and increase the time it takes for downloads to complete.
This problem is worse on Wi-Fi, because it is more prone to congestion. A router can only handle traffic demands on Wi-Fi sequentially, in a queue based system, and not simultaneously. More devices connecting equals more traffic demands, equals longer downloads, as the router can only do so much at once and has to keep everyone happy. However, there is a setting called Quality of Service or QoS, which you can try and use on your router to manage traffic and prioritize your PS4 on the home network.
This is a setting which can tell your router to handle all traffic demands from your PS4 first, before anything else. It is mainly used to reduce ping on busy networks; nevertheless you can try it if you like to see if it also improves download speeds as well at busy peak times.
Nevertheless, it is good practice to use QoS to reduce ping at least on busy networks, and may offer some help with download speeds. More generally, it is also true that downloads can run slower more generally at peak internet use time evenings and weekends , when lots of people are indoors and using the internet. One thing that can commonly catch people out is not realizing the difference between download speeds and file sizes.
This is something that caught me out when I was expecting a patch download to be completed in seconds when in fact it took many minutes. Put simply, download speeds from your ISP are measured in megabits per seconds, whereas file sizes are measured in megabytes or gigabytes, a much larger unit of data.
A bit is eight times smaller than byte, and therefore a megabit is eight times smaller than a megabyte, and a thousand times smaller still than a gigabyte. There are megabits in a Gigabyte so this gives some idea of why large downloads can take so long. Do you have the same question?
If yes, read the post in which MiniTool not only reveals the culprits but also shows you how to improve your download speed. Many users complain that the download speed is so slow that it takes a long time to download something. This can hamper both business and personal operations. Why is the download speed so slow? How to speed up PS4 downloads or how to make PS4 download faster? If you are looking for an answer to this question, this post is useful for you.
After trying these methods above, the download on PS4 will be fast. It is important to note that PS5 download speeds could also depend on internet speed. Better internet connection means faster internet, which can lead to faster download times. The current PS5 download times may not even be a problem to gamers who are used to slow download speeds on the PS4 due to their internet connection.
So while one player may experience slower download speeds, another player may see fast download speeds. If only the PlayStation 5 drastically increased download speeds like the Xbox Series X S did, Sony would have one less problem to worry about. The proper fix would be to implement them, and adjust the receive window of low-priority background downloads if and only if congestion becomes an issue.
That would actually be a pretty valuable feature for this kind of appliance. But I can kind of forgive this one; it's not an off the shelf feature, and maybe Sony doesn't employ any TCP kernel hackers. Fourth, whatever method is being used to decide on whether a game is network-latency sensitive is broken.
It's absurd that a demo of a single-player game idling in the initial title screen would cause the download speeds to be totally crippled.
This really should be limited to actual multiplayer titles, and ideally just to periods where someone is actually playing the game online.
Just having the game running should not be enough. I have no idea. Sony must know that the PSN download speeds have been a butt of jokes for years. It's probably the biggest complaint people have with the system. So it's hard to believe that nobody was ever given the task of figuring out why it's slow.
And this is not rocket science; anyone bothering to look into it would find these problems in a day. But it seems equally impossible that they know of the cause, but decided not to apply any of the the trivial fixes to it. Hell, it wouldn't even need to be a proper technical fix. It could just be a piece of text saying that downloads will work faster with all other apps closed. So while it's possible to speculate in an informed manner about other things, this particular question will remain as an open mystery.
Big companies don't always get things done very efficiently, eh? So idle that I hadn't even logged in, the app was in the login screen. The CDN that was being used from to was using a delay-based congestion control algorithm, and reacting to the extra latency by reducing the amount of data sent.
The CDN used earlier in the connection was using a packet-loss based congestion control algorithm, and did not slow down despite seeing the latency change in exactly the same pattern.

PS2 can not run any things in the background but I'm just curious about how it's networking stack works, being an older system.
Also has video apps like youtube, twitch and Netflix. Large companies don't really have mechanisms in place for feedback like this. Sure, one could send it to customer support or something like that. But the report will never reach engineering. The best one can hope is that somebody is keeping statistics on exactly the subjects people complain about, and once a quarter somebody looks at those statistics to decide what to prioritize.
And also, I think it's basically guaranteed that somebody at Sony is already aware of all the details in this post. Now if we could only find out why the PS4 "randomly" goes "LAN cable not connected" even though it damn well isn't.
Very interesting read. Could you share more detail on how you went about gathering the data used in the graphs? I took a packet capture on the next hop after the PS4.
This packet capture was then analyzed with a hacky perl script which just picked out the parts of the TCP header I wanted, and aggregated them by-connection at a 10s granularity. I doubt the code going to be useful for anyone, but I do like it as an illustration of just how simple this kind of ad hoc analysis can be even without explicit tool support. That's a good guess! Some sort of new failure of exactly that code is what I was hoping to find.
But unfortunately it's not the case. All of the connections were using TCP timestamps, but the autoscaling was not in effect at all despite that. They're clearly manually setting the receive buffer size with setsockopt , and that disables the autoscaling. I didn't check whether non-PSN connections had autoscaling enabled or not. Thanks for this very interesting blog post, BTW.. Have been annoyed by this particular set of issues for a very long time.
Strangely, I never thought that the software could be such an egregiously bad actor in this case. I think a more egregious issue is why the PS4 is so much slower over WiFi than over Ethernet - would it really just be congestion at the AP? But I think that ought to be demonstrably false when I can download at high speeds on a laptop that said, I'm most likely not using any of the same sources as the PS4. I honestly think that the set of devices released by Sony around the same time as the PS4 suffer similar problems - Currently, our TV cannot "find internet" over our WiFi, and that's when it manages to find and connect to our WiFi in the first place!
If they wanted to limit the rate of downloads it would make a lot more sense to set the allowed rate to e. Any thoughts on why Wifi speeds are just so slow? Is it a similar issue where the software caps speeds of downloads if the system sees it's on a Wifi connection? You're on the right track, except that it needs to go a step further. The allowed rate should not be static, like 1Mbps. It should actually depend on the network conditions.
The core goal of making sure background downloads don't interfere with games or streaming is reasonable. It's just that it's implemented in the wrong way, and triggered even when not necessary. If I understand correctly, I would not be able to notice these issues at all with my 5 Mbps adsl.
Welcome to Germany. Seems like a "feature" that only surfaced with the advent of high Speed internet. Interesting to have some figures on this matter although I thought everyone was aware of the fact that apps being open at all limited the download speed. That said I have apps set to be suspended in rest mode but have measured how fast the same download took Both with ps4 on and in game and in rest mode with game suspended and even accounting for changes in Internet bandwidth that occurred in that time period the download when in rest mode was almost twice as fast.
Something not explained by changes in Internet bandwidth. Out of interest I don't think you said we're you using normal Ps4 or ps4 pro? As the pro in theory has faster clocks peed on cpu which might effect how games using cpu effect any download limiting in those cases it also has the newer WiFi chipset I believe.
