port 80 download speed and browsing slow on three

Not sure if anyone else has the same issue but when downloading from a website i get extremly slow speeds down to 1-2mbps yes if i run a speed test or download a linux distro via torrent i get the full speed available to me such as 300-400 mbps

I have tried via a vpn yet speeds do not seem to change

should also add this is accross both APN's
 
My Three UK connection was found to be slow on a few occasions recently and I put it down to power-saving on an idle connection.

Some iPlayer and Apple TV+ streaming while using speedtest.net improved the situation for me.
 
Results taken within 30 seconds of each other

One is obviously a speedtest, the other is using rockstar download client, i can replicate this result with the EA app, downloading from google drive and also a port 80 speed test file

2.68 MB/s = 21.44 Mbps which is not terrible.

21.44 / 160.9 = 13.3%

Not all servers and services will be capable of maximising the throughput possible, and dedicated artificial benchmark tests can show higher numbers than throttled or congested services.

i get what your saying so after reading what you are saying i started a random torrent, from the result you can see speeds are around the same as the previous posted speedtest result

20.7 MiB/s = 20.8 (1024)^2 B/s = 173.6 Mbps

P2P can be very fast with popular files and many pieces being received in parallel in a distributed fashion.

Crowd-sourcing bandwidth in this way can beat some online services, especially around Christmas when many people may be downloading their presents.
 
A VPN hides all traffic from the network. When connected, the network doesn't know if you're downloading something from port 80. Unless the VPN itself works over that port, then you should see faster speeds if the network was slowing down a specific port.

Also, since most traffic is encrypted these days, you're likely seeing reduced speeds on port 443 (https), not port 80 (http) since most services - including some of those mentioned here like Google Drive, Apple TV, iPlayer, etc - encrypt their traffic/use HTTPS. Even this site does.

Could this be a... DNS problem? Speed test services usually do their own detection to find the nearest server (and Fast[.]com probably uses the Netflix caching servers hosted by the network). If the DNS server is returning IPs from CDN servers far away, then speeds will be bad for many sites.

Give it a try with Google DNS (8.8.8.8/8.8.4.4) or Cloudflare (1.1.1.1/1.0.0.1). You probably want to reboot the devices to make sure they're using the updated DNS servers. Also, if using a browser, make sure it's not using DNS-over-HTTPS as it bypasses the DNS from the network/system.

P2P traffic wouldn't be affected by a DNS problem since a torrent client tries to download from all available peers and doesn't rely on DNS.
