How much RAM do you need to run a Minecraft server?

Minecraft can be a lot of fun with friends, but the fun only lasts as long as you have a good playing experience. While the game itself will run fine on most PCs, running a Minecraft server is a different task altogether. 

A question that gets thrown around quite a lot when talking of Minecraft servers is the amount of RAM one needs to have a good experience. And the answer might not be as straightforward as you’d expect.

All things considered, if you’re looking to run a really heavy server with several different mods and want to have more than just a couple of players around, 2GB RAM should suffice. However, throwing more RAM at the problem might not be the solution everyone’s looking for, or in some cases, it might not be the best solution at all.


How to optimise Minecraft server software?

Instead of using vanilla servers, use alternatives like PaperMC instead. Paper contains a number of different performance optimisations and improvements that’ll significantly boost server performance without changing any hardware.
