Hi, i found here: https://docs.openvpn.net/getting-started/openvpn-access-server-system-requirements/ somthing like:

Memory requirements are highly dependent on the amount of connected devices,
and how much NAT traffic you're doing.
At the minimum we advise that you should start out with 1GB of memory.
.... you should add about 500 megabytes of memory per 100 connected devices.
So for a 1000 connected devices that would be 6GB of memory.

This question was answered by @ryanpq:

Openvpn does not use a ton of memory itself, somewhere around 70mb. Each user connected to this may then use 1-2mb more. Your results may vary but you should be able to get quite a few users on a 512MB droplet acting as a VPN server before you encounter problems.
