I want to start an MC server that I will code most things custom. I will try to create good community and bring people together. I'll start a small network while developing a whole gamemode in the background. The thing is that I have built some servers in the past, but these were, to make an understatement, really poorly made. I am now wondering, before getting started: How can I estimate the amount of ram I will need per server? Can you actually calculate this value or is it just trial and upgrade once lag starts to show.
