How do i create fake players like bots to join the server simultaneously to test my server performance?
Bots that just join and do nothing does not test the server's performance, they do not move, they don't run any commands, they just join however you could register your own human entity, and spawn 100 of them, and make them run around or break blocks or place blocks
you need a 3rd party client to spam players moving around to stress test using spawning via plugin may incur an not so accurate picture
