Running multiple instances of Xray-core

Hello, I have a question about the performance between running 100 servers on different ports within one.config and running 100 servers within unique configs (100 servers = 100 .config). That is, it turns out that in the second option there will also be 100 servers, but a separate xray-core will be launched for each of them.
The second option is preferable and better for me, and it's better, because I need to dynamically launch and delete proxy server instances, and if I restart the entire xray-core, then the connection will be cut off for all users. So, I would like to know, would such an approach be much worse for VPS/VDS performance?

wait, I think I found out that there is an API that allows you to add incoming connections. Is it so?
