So, 300 simultaneous connections, actively transferring data?

SoftEther has awesome features, compatibility and performance, except for scalability unfortunately

It should be fine below 250 active clients, source

Try out SoftEther
developer edition, a lot has changed since the above publication.

good article, but I do not think it is a good compression
- WireGuard has kernel support
- OpenVPN is old enough and stable
- ZeroTier is pear to pear not a client to server
- Tinc (I do not know about it)
SoftEther in its own category is the best. similar features with other tools are not free.
I think form the beginning they did not design it for enterprise uses cases and main focuses are on
- passing firewalls
- ease of use
- multi-protocols
There are many projects on Github, not as great as SoftEther, but they have more starts because not everyone needs a such VPN.
Hope it gets more attention and funding/sponsoring to get better.

It is better not register more than 300 users per a VM or machine since near 1/4 or 1/3 will connect simultaneously. (100)
Or at most 200 users simultaneously which means not more than 600 users registered
So scaling-out (more instance) is a better choice than scaling-up (more resources).
