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?
My WG traffic looked like a DOS attack to OVH and I got blackholed for 5min, then 15, then 30.
My guess is your provider is rate limiting your UDP traffic.
You could also try a VPS from hetzner and see if its any better. Here’s my speed test just now using WG on my cell, exit through Hetzner.
Is your test TCP or UDP? My guess is that’s TCP traffic.
Your VPS provider can rate limit as specific as a single UDP port. Try a different WG UDP port or wrap your WG traffic in TCP with other software and try again.
Having never used this software before, my guess would be your VPS provider is limiting the upload speed of the VPS. The data would be uploaded slowly to you, which means your download speed is limited as the client.
Meanwhile the upload speed is reported as being high enough, since the VPS can download your data at 50mbit/s, as this cap is higher.

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.
Have you tried running librespeed on the vps? Librespeed is good if you have a provider nearby. If not it is very inaccurate
