How much GFP for a MC server

[Trunks]

Minecraft server are free to run if you do it from your PC or server, they're actually fairly easy to run too, it doesn't take much. I ran one my computer so me and and a friend could do sky block together. You just have to allocate more RAM to minecraft for the server. I allocated 2 gigs for it, then left just a half a gig to run minecraft which is the default and had the other half free for what ever( only have 3 gigs cause xp sucks.) The server lagged down if I had a bunch of stuff running on my computer, but if it was just minecraft and the server it was fine. I only kept it up when we were playing on it though. Was lag free for 2 people, not sure what would happen if more people came in.

I don't really like to keep my computer running all the time, let alone stressing it by keeping a server running for 12 hours a day or so. So I can't really help you, but one of you should try hosting it your self and see how it runs, it may not be that bad.
