About this Modpack
🚀 SS Optimization Stack (1.21.11)
✨ Extreme Multithreaded Performance ✨
The SS Stack is a precision-engineered ecosystem for 1.21.11 🛡️. It eliminates CPU Bottlenecks, Memory Overhead, and Network Latency to ensure a constant 20 TPS, even during heavy exploration! 🌊

🧵 Multi-Threading & Dimensions
Minecraft is naturally "single-threaded." This section fixes that! 🧬
- Worldthreader: Assigns each dimension its own thread so the Nether never lags the Overworld. 🌍
- C2ME: Multithreads chunk generation to use every available CPU core. 🏗️
- ThreadTweak: Optimizes OS-level thread priority for the game's "Main Tick." ⚙️
🧠 AI & Server Governance
Entities are the #1 cause of TPS lag. These mods make them lighter. 🤖
- ServerCore: Features "Dynamic Ticking" to save the server during heavy load. 👮
- Lazy AI: Slows the "brains" of distant mobs to save CPU cycles. 💤
- NoMobLatency: Ensures smooth mob movement even on high-latency connections. 🐎
- Instant XP: Merges XP orbs to prevent entity-stacking lag. ✨
💾 Memory & Data Optimization
Stop "Garbage Collection" freezes and keep RAM usage low. 🐏
- FerriteCore: Drastically reduces memory used by block/item models. 💾
- ModernFix: A massive patch collection fixing leaks and code speed. 🔧
- World File Cleaner: Trims region files to keep disk I/O and backups fast. 🧹
- Noisium: Faster math for lightning-quick world generation. 🏔️
⚡ Technical Logic & Redstone
Optimized math for technical players and redstoners. 📐
- Alternate Current: A highly efficient, predictable redstone engine. ⚡
- ScalableLux: Moves lighting calculations to separate threads. 💡
- Structure Layout Optimizer: Fixes CPU-heavy structure lookup bugs. 🏰
📶 Networking & Utilities
Optimizing the handshake between server and player. 📡
- VMP: Reduces bandwidth usage and stabilizes packet flow. 📶
- Chunky: Pre-generate your world to eliminate generation lag entirely. 🗺️
- Debugify: Patches 100+ vanilla bugs that drain performance. 🐛
📋 Setup Checklist
- Java Version: ☕ OpenJDK 21+ (Java 22 recommended for C2ME).
- Dependencies: Requires Fabric API, Carpet, and ResourcefulConfig. 📂
- Target: Built specifically for 1.21.11. 🎯

How to Set Up a Serverside-Optimiser Server
Order Server
Choose at least 6 GB RAM (8 GB recommended for Serverside-Optimiser). Based on player count: per 5 players.
Install Modpack in Dashboard
Open the modpack browser in the dashboard, search for "Serverside-Optimiser" and click "Install". The fabric loader and Minecraft 1.21.11 are configured automatically.
Start Server & Play
Start the server – all mods are loaded automatically. Share the server IP with friends and play together!
Frequently Asked Questions
Serverside-Optimiser server crashes or won't start – what to do?
Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.
How much RAM does a Serverside-Optimiser server really need?
Minimum 6 GB, recommended 8 GB for stable performance. per 5 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €12/month).
Can I add custom mods to Serverside-Optimiser without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.11). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
Serverside-Optimiser server lagging – performance tips
1) Increase RAM to 8 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
