I've recently started my own server and I'm constantly paranoid that I'll end up doing something wrong that will mess something up, and right now I'm not sure if I have too many plugins installed or if it's a problem that I'm creating many different worlds with Multiverse. I just want to know how to check my memory usage :] More info: - My server is running off 2GB RAM at the moment. - I have around 15-20 plugins. - I have 3 different worlds with multiverse. Am I safe?
