I bought VPS and configured wg-easy, but speed for download is too slow, while speed for uploading is not so bad. Why this might be happening?

    Could be an ipv6 issue in which case reducing the MTU might help

      Yeah I’d check for fragmentation, particularly coming from whatever was on the opposite end of this tunnel. This looks like librespeed (which is super simple to run in a container, ‘adolfintel/speedtest‘, if interested…I run some at work and it’s very useful) so I’m assuming it was running on the server at the other end of the wireguard tunnel?

      That latency and jitter are also absurd tho. Op should run a bufferbloat test on both sides. Though I don’t always trust those results from librespeed.
