Welcome! This guide walks you through optimizing your Minecraft server. Whether you run a small private server or host friends, this guide helps you make your server run faster and smoother. It covers settings and tips for popular server types like PaperMC, Pufferfish, Purpur, and Spigot.
You don’t need to be a programmer or know code. This guide uses clear steps and simple terms to help you improve your server's speed and reduce lag. We'll explain how to adjust Java settings, install plugins, and change files safely.
Topics covered:
- Basic server setup tips
- Using Java argument files for better performance
- Key server flags and options explained
- Popular optimization plugins
- How to tune different server types
Use this guide to reduce lag, improve player experience, and keep your server stable for hours of gameplay.
Before you start, gather the following:
- A computer with Windows, macOS, or Linux.
- Minecraft server files, ideally using PaperMC, Pufferfish, Purpur, or Spigot.
- Access to your server folder and ability to edit files there.
- Basic knowledge of locating files on your computer.
Hardware suggestions for best results:
| Server Size | RAM | CPU Recommendation |
|---|---|---|
| Small (up to 10 players) | 4 GB RAM | Dual-Core 2.5 GHz minimum |
| Medium (10-50 players) | 8 GB RAM | Quad-Core 3.0 GHz |
| Large (50+ players) | 16 GB or more | Hexa-Core 3.5 GHz or better |
Having enough RAM and a good CPU helps, but many improvements come from optimizing your settings.

Java arguments tell your server how to use memory and CPU power. This guide explains which flags (small bits of text) to add and why.
Common Java flags covered:
-Xmsand-Xmx: Control minimum and maximum memory (RAM) for the server.-XX:+UseG1GC: Uses the Garbage Collector that improves performance.-XX:G1HeapRegionSize: Helps with memory management, important for big servers.-XX:MaxGCPauseMillis: Limits how long garbage collection can pause the server.
We explain how much memory to allocate based on your hardware and player count.
Minecraft servers come in different flavors. Each has unique files and tuning points.
PaperMC
PaperMC is a fast, optimized version of Spigot. The guide shows you which Paper settings affect performance like entity limits and tick rates.
Pufferfish
Pufferfish builds on PaperMC with extra fixes. The guide helps you find and tweak its config files to get smoother gameplay.
