Hard limit of 1Gbps?

[Server73 0]

While using AirVPN I am unable to go any higher than exactly 1Gbps. I am on a 2.5Gbps uplink, and can fully saturate it without AirVPN without issue. I am connected to a 20Gbps server that is not under any kind of load, and my MTU is set to 1280, which is what I need for a low retry count. I am using a server that is geographically very close to me. This doesn't make much sense to me 😕

Hello!

There's no "hard limit", as correctly advertised on the main page. The main factors determining the maximum throughput are the physical limits of your ISP and our lines/ports/server available bandwidth, CPU power, the weakest (slowest) hop in the network path between your and our nodes, and traffic shaping by your ISP (if any). The "weakest" of the mentioned factors determine the actual throughput. In reality the all time high recorded in AirVPN history (WireGuard only) is more than 1 Gbit/s: about 2.1 Gbit/s from residential lines around the world (also confirmed here) which means 4.2 Gbit/s on the server for that single session, and even more from datacenter to datacenter.

Kind regards
