Ask HN: WireGuard Traffic Under Load Hey, I had my wireguard connection really slow while other stuff worked relatively ok today so calling the isp I was told that possibly it’s related to a new fortnite release. How common for you to experience drastic slowdown of wireguard or other udp traffic when your isp is under load? |
A relative statement, without an indication of what you are measuring against, is of no value.
Then that does sound like your ISP may be de-prioritizing UDP data, or specifically throttling UDP flows to some level 10x smaller than your full bandwidth.
Are you sure, however, that the other end of the VPN connection is not where the slowdown is happening? If that end was the choke-point, you'd still see slower traffic but your ISP would not be the reason.
