try to measure cpu load during benchmarks, you may be surprised.
also make sure to use kernel module for wireguard

Try to measure CPU load during benchmarks, you may be surprised.

It maxes at 45% using both of my devices at the same time.

also make sure to use kernel module for wireguard

I don't know even what that is! Doesn't this script do it automatically?

what i OS you use and System arch, Debian/Ubuntu with arm64 arch loss many connection's and depend you VPS config more loss connection

@Sirherobrine23
Ubuntu 22.04 and Ubuntu 20.04 amd64
2 vCPU (NOT SHARED) 3.5 Ghz 1.5 GB RAM

Client: Single user 2 devices Fiber to the premises ethernet Cat.7 2023 PC parts (Windows OS).

No other factor can cause this, both client and server are in the most optimal conditions, I would not bother opening an issue otherwise.

@wyntrson Wireguard windows client will have a loss of connection because it is not a direct connection by the kernel, in windows it is fully operated by the Windows userland, in this it will have a significant loss

@Sirherobrine23 Other WireGuard connections deliver 95% of speed 5% loss on my windows machines.

@wyntrson Have you tried using iperf to test a direct connection to your machines without going through wireguard?

from wireguard-install.

Direct conenction:

With Wireguard connection:

Config: 4vCPUs (arm64), 24Gb Ram, Ubuntu 22.00.

htop:

My conenction with wireguard and direct not loss connection download and upload, recommend check vps config.

@Sirherobrine23 I did the same with iperf3 and got the same results as you. Almost no loss. What VPS config do you have in mind?
Why when you use a wireguard connection from NordVPN, SurfShark, ProtonVPN the speeds have no overhead, almost the same speed as the connection?

from wireguard-install.

@wyntrson something that happens a lot is the latency between connections, so you send the request to the server foo and foo will have to connect to the bar to get a return, in addition, Wireguard uses UDP to transfer data, which is a Of the various factors for connection and packet loss, other vpn protocols use TCP for their connections. i have considerable packet degradation

My config is Oracle Cloud 4VCPUs with 24Gb of Ram, 24 Clients

My house to Server locations is 230~300 Km (São Bernardo to São Paulo)
