Hi, I'm planning on running a 24/7 Minecraft server from my oldish (Mid 2010) Macbook. I have 4 GB of ram and currently expect to have 8-12 plugins. Some people may be using the laptop for internet purposes occasionally, but I've informed them to leave it open and not to touch any files. Anyways, how many players do you recommend I allow on at a time? I don't expect it to be a huge server, but I don't want to fill it with too many people at one time. Any suggestions?
