So I've had this Minecraft server for a long time that I just play on with friends using Hamachi. I've always used the free version of Hamachi, which only allows up to 5 players to be in the group, but I am considering buying the large version of it which can have up to 30 people. This would allow me to have more people on the server at once.
So my question is, does having more people on my Minecraft server use more of my computer power? Whenever I have my server up, my computer fan is running like crazy and it makes other games lag and stuff run slow because of all the energy it is using, so if I have more people actually on the server will it run my computer any harder?
Note: This is just a simple vanilla Minecraft server that you can download from Minecraft.net No Bukkit or anything.
