Optimize Your Minecraft Server Performance

A laggy server is frustrating — whether you’re running a big modpack or just playing with friends. Fortunately, there are some smart optimizations you can apply to boost performance significantly.

🔧 1. Choose the right Minecraft version

Not all Minecraft server types are equal. Here’s what we recommend:

Version	Best for	Notes
Purpur	Survival / Minigames	Very fast, supports plugins.
Paper	General use	More stable & optimized than Spigot.
Forge/Fabric	Modded servers	Heavier, needed for modpacks only.

🛠️ 2. Adjust `server.properties`

A few config changes can instantly reduce load:

view-distance=6
simulation-distance=4

🧠 3. Java startup options? Already optimized

You don’t need to worry about JVM flags or launch arguments.

🧪 At OXY.Games we configure these automatically based on your package size.

🧩 4. Remove unnecessary plugins or mods

Every extra plugin or mod uses CPU and RAM. Ask yourself: do I really need this?

❌ Avoid plugins like ClearLag (often counterproductive)
✅ Instead, use:

Spark – performance analysis
Lithium / Starlight – optimization mods for Fabric
Chunky – chunk pre-generation

📉 5. Analyze with Spark

Spark helps identify lag spikes and performance bottlenecks.

It shows:

🔥 TPS and CPU usage per tick
📊 RAM usage, loaded entities
🧠 Breakdown of slow tasks

📘 Full guide coming soon.

⚙️ 6. Tune your Paper or Purpur configs

Edit these config files for more control:

`paper.yml`

optimize-explosions: true
armor-stands-tick: false
anti-xray:
  enabled: true

`spigot.yml`

ticks-per:
  animal-spawns: 400
  monster-spawns: 1
  water-ambient-spawns: 1

`bukkit.yml`

chunk-gc:
  period-in-ticks: 600

🤖 7. Monitoring & AI Assistant (Coming Soon)

Soon, OXY.Games will offer an AI assistant to analyze your logs, detect crashes, and suggest optimizations.

Until then:

Check your console for errors
Use /spark for live profiling
Use /timings on then /timings paste

🧱 8. Pre-generate your world (chunks)

Exploring new terrain generates chunks — which can lag the server.

Preload them with tools like Chunky (for Paper/Purpur):

✅ Install Chunky

Install the plugin via the panel
Restart your server

🔍 Commands

/chunky radius 250
/chunky shape square
/chunky start

❄️ Fabric/Forge Alternative

Use Chunk-Pregenerator mod:

Install via “Mods” in the panel
Use /pregen commands
