Set up a Minecraft server on a Raspberry Pi.
Set up a Minecraft server on a Raspberry Pi.
It should function effectively—though not perfectly. The quad-core processor is probably sufficient for the server, but the 1GB of RAM might become a significant constraint on performance and stability. I recommend purchasing an affordable PC from Dell or HP on eBay and using it. Make sure the machine has at least 4GB of RAM and a quad-core CPU.
The importance of quad-core processing is minimal. What a server requires is strong single-thread CPU speed. Yes, newer releases with many cores can help, but Minecraft servers continue to prioritize single-thread efficiency rather than multi-thread capabilities.
It's feasible using optimized server setups like Spigot. You can allocate as much RAM as needed without triggering swapping (~650MB) unless you're running on a Pi. Store the server world on a USB stick to isolate IO demands from the SD card. Verified with 6 players, no mods, and WiFi connectivity.
I recently upgraded my server with a modded setup. Prior to the change, everything was running smoothly—very little lag and no TPS problems. Before the upgrade, my system had an Intel q8200 processor, 4GB of RAM, an older 775 motherboard, and ran Ubuntu. The total investment was $60, covering the HDD, power supply, and case. Keep in mind, some modpacks need more than 4GB of RAM!
