From my /r/TechSupport reddit submission:
All computers referenced in this post was done on a ethernet connection
I have been suffering this issue for the past few months without any solution available. When I download anything (especially from a few specific servers) the download speed never goes above 1-2 megabits (~200 kilobytes per second) a second. However youtube is able to play the video back at around 30-60 megabits per second, whilst speed tests from various websites both report back 90 megabits down and 35 megabits up which is the maximum speed capable of my semi-fibre connection.
I am fully aware that download speeds are dependent on the server that is being used to download a file from (eg server load) and how well the ISP peers with other networks but here is some more info. I downloaded a file from the same server on a different computer and is able to reach around 10-12 megabits per second which I expect as there is around ~300 millisecond latency between me and the server as its in a different country. However on the PC with the issue, downloading the same file off the same server will only reach speeds at around 1-2 megabits per second. To isolate if the issue is with the operating system, I decided to reboot into a live ubuntu usb stick on the problematic PC and downloaded the same file from the same server there and it is able to easily reach around 10-12 megabits per second, which is the same with the other PC I have tested it with.
Some other tests I have done included an iperf3 test, a network bandwidth test tool. I have set up the iperf3 server on a VPS and the client on both the problematic PC and the other computer. Here are the results:

iperf Done.
On the problematic pc, the download seems to be capped at 187 kilobytes per second compared to the other computer where it is sitting at around ~770 kilobytes per second.
Another test I have done was to setup a ftp server on both machines and sent a file to both of them from the VPS and the problematic PC stayed at around 190 kilobytes per second and the other computer was at around 700-800 kilobytes per second.
From all my findings it seems to be an issue with the operating system. Not the computer its self. Currently I still do not have a fix for this issue. It would be greatly appreciated if some one could provide some input into this issue.
