Advanced Minecraft Lag Machine Detection & Protection
LagMachineDetector is an advanced, lightweight and production-focused Minecraft server protection plugin designed to detect, analyze and identify performance-abusive machines before they seriously affect your server.
Built for Paper & Folia, LagMachineDetector analyzes machine behavior, activity frequency, server performance impact and surrounding structures instead of relying on simple block-count rules.
Detect the machine. Understand the behavior. Protect the server.
⚡ What Does It Detect?
LagMachineDetector can analyze suspicious activity from:
- 🔴 Redstone clocks
- 👁️ Observer loops
- 🔁 Repeater loops
- ⚙️ Comparator loops
- 🟩 Piston machines
- 🧱 Sticky piston machines
- 🚀 Flying machines
- 🍯 Honey-based machines
- 🟢 Slime-based machines
- 📦 Hopper-heavy systems
- 💎 Item-spawning machines
- 👾 Entity-spawning machines
- 🚂 Minecart-based systems
- 🪨 Falling-block machines
- 💧 Fluid-update machines
- 🌍 Chunk-loading abuse
- 🌎 Chunk-generation abuse
- 🔄 Excessive block-update machines
The plugin focuses on behavior and server impact, not simply the presence of certain blocks.
🧠 Intelligent Detection
LagMachineDetector does NOT use simplistic rules such as:
❌ "Piston + Slime = Lag Machine"
or:
❌ "Observer + Piston = Lag Machine"
Instead, it analyzes multiple signals:
Machine Structure
↓
Activity Frequency
↓
Repeated Behavior
↓
Resource Usage
↓
Server Impact
↓
Farm Detection
↓
Risk Score
