🚀 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:

VersionBest forNotes
PurpurSurvival / MinigamesVery fast, supports plugins.
PaperGeneral useMore stable & optimized than Spigot.
Forge/FabricModded serversHeavier, needed for modpacks only.

🛠️ 2. Adjust server.properties​

A few config changes can instantly reduce load:

view-distance=6
simulation-distance=4
🎯 Why?

Lower values mean fewer chunks loaded per player. For most setups, 6 is a great balance.

🧠 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.

Did you know...

We use JVM flags tuned for stable memory use and minimal lag — even with busy servers or modded worlds.

🧩 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

⚙️ 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
✅ Extra performance

These tweaks reduce tasks per tick — especially useful for large servers or mob-heavy worlds.

🤖 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​

  1. Install the plugin via the panel
  2. Restart your server

🔍 Commands​

/chunky radius 250
/chunky shape square
/chunky start
💬 Tips
  • Run when the server is empty
  • Temporarily disable backups
  • Monitor CPU while generating

❄️ Fabric/Forge Alternative​

Use Chunk-Pregenerator mod:

  • Install via "Mods" in the panel
  • Use /pregen commands
