You’re ignoring the fact that most areas of the US are hamstrung by super shitty asymmetric up/down bandwidths (fuck you very much, Comcast). I have 1.3gbps down… and 30mbps up, per the contract.

If one upload slows down your internet you probably need a router that has a better packet scheduler. I recommend you look for one that uses FQ-CoDel

Why don’t you switch to a different ISP? Last time I checked I could choose from 13 different ISPs on fiber alone, and that’s in ‘socialist’ Europe. I can’t even dream of how many options someone in ‘free market’US must have.

Regulatory capture means that a shockingly high proportion (I’d be willing to bet it’s a strong majority) of unitedstatesians have precisely one viable option for an ISP with meaningfully high speed.

Does uploading slow down downloading? I thought the two processes were totally decoupled. How does this work?
BorgDrone@feddit.nl 1 day ago
Yes, it can slow down downloading.
(The explanation below is simplified quite a bit)
When you download the server that is sending you the file doesn’t just dump all the data onto the network in one go. They don’t know how fast you can receive and it’s not like the routers along the way will buffer large amounts of data. It needs to figure out how fast it can send.
So how does it do this? The sender sends a few packets of data and then waits for the receiver to acknowledge reception before it sends more data. Now the acknowledgment message isn’t that big so when downloading the amount of data sent back (uploaded) is just a tiny fraction of the amount downloaded, so that usually doesn’t matter.
The problem occurs when your local network is much faster than your internet upload and your router isn’t smart about which packets to send first. A good router will not allocate all the spots in the outgoing queue to the connection doing the large upload and instead will make sure the connection with smaller amounts of outgoing data will get a fair turn.
If your router isn’t smart like that the ‘data received, please send more’ packets may be delayed and thus slow down the download.

If your router’s cpu is locked 100% because of an upload it can’t handle additional download, probably. This could be improved with a more powerful cpu or a more efficient process of sorting out up- and downloads. At least that’s what I got from the original comment. I’m not a networking expert (far from it) so take this with a big grain of salt.

On the ISP end sometimes non symmetrical equipment is used, especially on copper coaxial which are used much like “wired wifi” in that data is transported by encoding it into frequency bands. Each frequency band can only be used up OR down per cable, so ISPs tend to dedicate more frequency bands to the downlink than to the uplink.
And as others mentioned, the commonly used TCP protocol will slowly ramp up bandwidth by having the server send a burst of packets, the client acknowledges, then the server sends more packets faster and the client acknowledges again, and once the client and server starts noticing packet losses it backs down and resend the lost packets a bit slower, until the connection bandwidth is stable.

I’ll play. Without assuming where anyone is from, I’ll add that the vast majority of US residential Internet connections, especially those in rural areas, are not only slower than they are in much of Europe (for example) but are commonly asymmetrical, too. Meaning even if someone has a gigabit connection, often it’s only 1Gbps in one direction for Americans while the maximum upstream throughput may be closer to 50Mbps. Even a top-of-the-line, 5 figure Cisco or Juniper router can’t do much to improve that situation for the end user when someone starts uploading large video files.

So… we shouldn’t learn about things because the internet in the US sucks?
bleistift2@sopuli.xyz 1 day ago
I believe every internet connection in the world is asymmetric. Most people download way more than they upload.
