Solving lag on a server?
Hello!
I have a pretty low pop server with 39 plugins. When the server gets to ~25 pop it starts to run into huge lag spikes. Players freeze in their locations and when the server comes back everyone spams "lag" in chat. This happens every couple of minutes. Not sure how to find the cause of this problem, but I suspect it is one of the plugins. How can I find which plugin is causing this? Is there another fix? Thanks!

Edit: I did some more research, and I get huge server FPS drops when players are killed and enter the game.
