This guide provides some suggestions on how to determine how much RAM you need for your server. However, if you’re not sure which plan to choose, that’s certainly okay! We allow you to upgrade or downgrade at any time, so if you find you don’t have enough RAM or have too much RAM, you can adjust your plan by paying only the prorated amount (the difference between the packages). Additionally, if you’re downgrading, our system will automatically issue a prorated refund for you.
Vanilla / Craftbukkit / Spigot
Add 1GB of RAM per 20 players
Add 1GB of RAM per 20 Plugins/Data packs
Add 1GB of RAM per 20 plugins
(Some plugins are far more resource-intensive than others, so depending on which plugins you’re using, you may need additional memory. Some very resource-intensive plugins are: Dynmap, WorldEdit, MCMMO, Factions, and many minigame plugins.)
Add 1GB of RAM per 2GB world size on disk (The size of your worlds and amount of players exploring them heavily influence the impact of a world.)
Modpacks, Forge, Technic, KCauldron & Any Modded Server
We recommend at least 4GB of RAM for any modded server. Modded servers are very resource-intensive and use large amounts of RAM. If you plan on installing many mods or large modpacks, you may need to add even more RAM to your server to prevent lag.
