So I need to host 4 Minecraft servers on my VPS. The VPS is a node on a pterodactyl panel that my friend is hosting. I want to dedicated 750mb - 1gb of ram to the websites I'm hosting on it. My VPS is a 4gb of ram VPS. So this is my current configuration: 500mb - BungeeCord Server 500mb - VERY SMALL Hub server 2gb - Main Spigot Server My (different) friend has another VPS which will host the other servers in the network. MAIN QUESTION: Is there anything I can improve about my current configuration, RAM wise? Please don't talk about my CPU, or anything other than RAM.
