GL.inet - OPNsense Wireguard VPN Slow

[litusbdn]

Good afternoon,

I have installed a GL.inet Brume 2 / GL-MT2500 router.

According to the manufacturer, in client mode Wireguard can reach speeds of 500mb/s. https://www.gl-inet.com/products/gl-mt2500/


On the other end, I have an Opnsense 23.1.9, installed on a physical server with 128GB Ram, Intel(R) Xeon(R) Silver 4316 CPU @ 2.30GHz (20 cores, 40 threads).

I have managed to configure the wireguard tunnel successfully and there is traffic between the local and remote network.

The main problem is the speed of the tunnel, it barely reaches +-30mb/s over a 1GB/s optical fiber. I have been modifying the MTU's and I can't find the parameter that can increase the speed.

Can you tell me what I can check to optimize the maximum speed?
I need to be able to create tunnels with a minimum speed of 180mb/s approximately.


If you need any extra details, I will be happy to send them to you.


Thank you very much.

If it's SMB transfer, it's due to Internet latency. If you're testing with iperf, have you tried multiple thread?
