    Its not from the downloading in itself, its from the decompression.

    Being bottlenecked by your cpu when downloading is a godlike experience

    Holy fuck, 110MB/s network speed, i’m using wifi 6 and only have 22MB/s peak

    Considering we could saturate Gbps Ethernet before the days of 20 Thread processors, it’s safe to say it’s not the downloading that’s causing high CPU usage.

    i had an old laptop and when i was downloading games from the university’s internet the hdd was the bottleneck lol

    my steam download speed 2.4 mb/ps someone streaming youtube drop to 2 mb/ps 🙂 100 mbps is very fast i mean 6 gb minute 60 gb hours

    I’m sorry… How Fast?! I get 500kb/s download speed lol

    No, it does not go to 100% when downloading unless you have a bad third party firewall that uses that much CPU at high transfer rates, or your LAN driver is borked and it is not properly offloading stuff to the LAN chip and CPU has to do that.

    Or that is just decompression…

    But yes, in other news… when moving to a new place the Tier List of priority is:

    1. Electricity
    2. Gigabit fiber
    3. Running water
    4. Sewer
    5. Heating

    And one might argue 1 and 2 can be flipped around. You could just get a diesel gen to fix #1, but there is no real fix for #2 if it is missing. Only temporary hack might be a Starlink dish, but that requires a big open space, to see the sky, so not always feasible. And it is nowhere near gigabit…

    I’m so incredibly thankful to have Fiber. Especially considering I live 20 minutes outside the city limits, surrounded by cows. One of the biggest lucky breaks ever.

    But that speed isn’t really nearing the 1 Gbps limit, 108.3 MB/s is around 866 Mbps. Is it possible for the CPU to be the one causing it? But since that kind of usage is most likely to be coming from the Steam’s decompression, now im curious about it.

    Or is it normal for your fiber to never/rarely actually hit the 1 Gbps limit overall on any devices?

    Asking real curious questions here since it’s still years to come for my country to have gigabit internet for individual / home use. 😅

    Even if let’s say I have the money to pay for gigabit subscription, 100 Mbps is kinda the limit here. Anything beyond that is strictly for offices/big groups/commercial like malls and whatnot.

    I have a 1gbit/s almost 2 years now and found out last month they upgraded it from 350mbit as i had 2 years ago 🤣

    i wonder if the cpu bottlenecks your internet speed to give itself time to decompress and install everything and/or the download doesnt give a flying fuck and keeps downloading at high speeds and let’s the cpu do its thing at its own speed

  20. njay80

    yeh that got me too, whys my fans going mental its just downloading lol

    My sata ssd chokes on download speed of 100mbps

    I have a i7 4770k on an almost 10 years old computer with a SSD on S-ATA.

    I maxed out at almost 300MB/s (which is roughly 2,4Gbps) on the Frankfurt servers (I still have the screenshot).

    The CPU is overclocked at 4GHz and was screaming the whole time (for the download alone, not talking about the extraction. I had the same with [fast.com](https://fast.com) where I went 9,1Gbps with all cores at 100 %).

    ​

    Also, it’s very hard to max out your connection since most games download by “chunks”, so download, pause the download to extract and resume which doesn’t let the speed goes up enough. Only a few games allowed me to go that high, those who download the whole things in almost one sitting and then extract.

    ~~I can’t tell if you’re being limited by WiFi strength or just how the speed is at your place, I got fiber too and download around 800mbps, sometimes 100 or so less.~~

    Edit: nvm, just saw it’s MB not Mb

    Some 20 years ago, with my first dsl connection and in the emule era, there was the belief that loading the CPU with intense workload would make downloading much faster. And it surely did, and it’s still puzzling me
