How much RAM do I need?
Various amounts of RAM will be needed for different Minecraft servers depending on their setup and intended use. A Minecraft server’s performance will suffer or even crash if it has less RAM than it requires, so it’s critical to know what factors influence RAM usage and how much is required. A server will typically require more RAM the more players and addons (mods/plugins) it supports.
A reminder that the following values are only a suggestion and its always better to have more RAM.
