Stress testing Multiplayer - How to imitate players?


I would like to know if it’s possible to somehow run the client without renderer (sort of like dedicated server does) so I could stress test my multiplayer game (I’m thinking about 15+ client activity-resembling bots or more on a single machine, multiple machines).

If it’s not possible, what would you recommend for this kind of thing? Any advice would be greatly appreciated.

This would be tough with the editor since when it simulates clients, it run multiple instance of the game on the machine. This makes the machine become the bottle neck instead of the server. To get a good indication. I would run the server on one machine then right a script that slams the server with thousands of requests and see how fast the server handles a request for a given load.

I would recommend reading the below, this is where I learned queueing theory and stress testing:
