Why does uploading something cause browsing the internet to be so slow?

I have a pretty decent download speed, and a upload speed 20x slower then it. So even if I am uploading at max, how can that affect my download speed.

Well, I have only ever noticed while browsing. I believe I can still download at high speeds while uploading, its just browsing. Why?

So if your upload pipe is FULL, how do you go and request a new page from the server, how do you even look up the site via dns if your upload is full.

Does not matter if you have 10GB down, if you use up your upload side -- you can never ask some server to send you that next page, or even look up the address of that web server, or email server, or ftp or whatever, etc.

No. Communication is two way, up and down, in and out.

Find a way to have one way communication regardless of the medium (telepathy, simple conversation, etc) and you will have ascended to a new plane of existence where things/people/anything knows what you want without telling, thinking, moving, or doing anything other that sitting still.

If using all of your avail bandwidth to upload or download you either will never be able to ask the question/make a request or be able to get an answer/get the file.

The one thing flawed is that many isps give you a very small upload pipe compared to your download ;) All fine and dandy they say you have 100GBps down, if your upload is only 100KBps ;)

Depending on your ratio its even possible that your upload limit might make almost impossible to actually reach your download speeds. With the way tcp works, you have to ack back during your download. So at some point your upload pipe will be maxed out, and you can not send acks any faster.. Even though it might be possible to download faster per your stated speeds.

This issue you have just recently discovered ;) Is why so many users ask why does p2p slow down my browsing! Because they never bother to correctly setup their clients to leave some room on their upload side for stuff like dns, or http requests to neowin saying you want to view this url, etc.

If you correctly setup your p2p to use only a % of your upload bandwidth, and not the whole thing - then its possible to continue browsing, emailing, ftping, etc. etc. without any issues - because its still possible for you to ask dns where www.something.tld is or send that request to neowin http server for the next page of the forum section your reading, etc. Or to send to google that you would like to search for whatyamacallits

If you want to fully use your upload pipe sending bits of something to the swarm members, or sending your latest cat video to youtube then you could setup some QoS on your router that says hey I know your queue is full of sending out p2p stuff, but I have this dns request I would like to send right now - please let it cut in line. In simple terms that is what QoS (quality of service) is -- the ability to cut in line, and create different lines (queues) for different protocols. Kind of like fast pass at the amusement park ;)

    • I do trust Apple probably more than these other companies with certain data, but I also do think (and it has been demonstrated that) Apple pulls a lot of shenanigans and always has for a long time.
    • Does your iPhone support the latest iOS version? Here's the iOS 27 compatibility list by Aditya Tiwari It's that time of year when we get to know about the latest operating system updates for Apple devices. For iPhone, Apple previewed the iOS 27 update at WWDC 2026, where the company finally introduced an upgraded version of Siri. Apple typically supports iPhone models for up to five years. But it has been making exceptions in recent years (read iPhone 11). If you're wondering whether your iPhone is compatible with the iOS 27 update, here is the official list of devices: iPhone 17 Pro Max, iPhone 17 Pro, iPhone 17, iPhone 17e, iPhone Air iPhone 16 Pro Max, iPhone 16 Pro, iPhone 16, iPhone 16 Plus, iPhone 16e iPhone 15 Pro Max, iPhone 15 Pro, iPhone 15 Plus, iPhone 15 iPhone 14 Pro Max, iPhone 14 Pro, iPhone 14 Plus, iPhone 14 iPhone 13 Pro Max, iPhone 13 Pro, iPhone 13, iPhone 13 mini iPhone 12 Pro Max, iPhone 12 Pro, iPhone 12, iPhone 12 mini iPhone 11 Pro Max, iPhone 11 Pro, iPhone 11 iPhone SE (2nd generation), iPhone SE (3rd generation) So, you can download the iOS 27 developer beta on up to 31 different iPhone models. There has been no change to the list of supported iPhones since iOS 26. However, it will expand to include more devices when the iPhone 18 series arrives later this year. To download the developer beta on your iPhone, go to Settings > General > Software Update > Beta Updates. Here, select "iOS 27 Developer Beta" from the list of choices to get the new update. In addition to iOS 27, you can try the developer beta versions of macOS 27, iPadOS 27, watchOS 27, tvOS 27, and HomePod software 27 on your supported devices. iOS 27 comes with improved Liquid Glass, which you can adjust using a new transparency slider. Apple said during the keynote that iPhone apps now launch up to 30% faster, new photos appear in the Photos app up to 70% faster, and AirDrop transfers work up to 80% faster. The new update promises to improve performance on older iPhones by introducing a new CPU Scheduler that supports devices all the way back to the iPhone 11. While iOS 27 is supported on older iPhones, it goes without saying that they'll lack several features due to hardware differences. For instance, iPhone 14/14 Plus and older models come with a notch instead of the Dynamic Island. Similarly, Apple Intelligence features are supported on iPhone 15 Pro/Pro Max and later models.

    • I don't know why someone said useless, but it does have that pesky kernel driver bundled, and it's in perennial turmoil. When it goes bad, it goes very bad, and it's impossible to predict when it will due to system differences. I know that they're in the middle of development for a major new version that will include a completely new driver, one that they expect will largely solve the problem, but that's a ways out and it's unproven at this point.
