OpenVPN on VPS (1GB RAM) only getting 50Mbps down on 300Mbps connection

Hi @L9

You should not expect to get the same speed as a connection without VPN. That being said, it depends a lot on the encryption level you use and amount of CPU power available on the server.

Working with firewalls, you can easily get 1GBit bandwidth on modest hardware, but if you run VPN on the same hardware you get 40-140Mbit. The main reason for the difference in speed coming from whatever encryption level is being used.

I currently can’t test anything from my location, because I’m lucky if connections in this country are stable - and if they are, they’re not more than 10Mbit. Maybe someone else will pitch in with their experience on running VPN on DO with higher connection speeds.

@L9

I’ve honestly not used OpenVPN in some time since being introduced to Algo, which makes setting up a VPN far easier than doing it manually (at least on MacOS – not tried it on Windows 10 yet).

It provides direct deployment to DigitalOcean, your choice of DC, by simply providing a key.

Algo is IKEv2 only, so you definitely need an OS that supports it – Windows 10 and MacOS does.

…

I’ve tested the setup that Algo uses on 60-150 Mbps connections and I consistently receive 98-99% of the connection speed in all three of the NYC data centers (i.e. 60-150 Mbps).

Last I used OpenVPN, my results varied from between 50-60% up to 80%, though I never saw what I see with IPSec/IKEv2.
