Want a more efficient method of authentication

The current authentication method inevitably has some performance problems in scenarios with a large number of users
Are you considering using other methods (such as RSA) in a future release to verify the user so that no matter how many users there are, it won't affect performance

The ask is valid, but are you facing real performance problems?

A benchmark shows in my cheap VPS, it can handle 25k authentications computing per second. We also have the caching of authentication cipher blocks. So in real world I think the current implementation is able to scale up to 100k users per VPS.

I'm just worried about this, I haven't put it into a real project yet, I'll test it later.
There was another problem, I had to group the users because when handling too many users I got the following error
set mita server config failed: rpc error: code = ResourceExhausted desc = grpc: received message larger than max (4977817 vs. 4194304)

@satel-global I opened bug #166 to track the grpc error.

Thanks

Another concern I have is that if the attacker sends a large number of verification requests, it will immediately overload the server. Shadowsocks has the same problem.
