Smart Optimizer

A Bukkit/Paper plugin that dynamically optimizes your Minecraft server based on real-time RAM and TPS usage.

gravel host

Features

Hardware Detection

- Monitors RAM usage using `Runtime.getRuntime()` - Tracks TPS using `MinecraftServer.getServer().tickTimes` - Real-time performance metrics collection

Dynamic Scaling Levels

Level 1 (Healthy): - Triggered when RAM usage < 70% and TPS is 20 - Maintains View Distance of 10 and Simulation Distance of 8 - All mob AI enabled

Level 2 (Moderate): - Triggered when RAM usage > 80% or TPS drops to 18 - Reduces View Distance to 8 and Simulation Distance to 6 - Disables AI for distant mobs (>64 blocks away)

Level 3 (Critical): - Triggered when RAM usage > 92% or TPS drops below 15 - Reduces View Distance to 5 and Simulation Distance to 4 - Pauses non-essential mob AI - Clears ground items older than 2 minutes

Visual Integrity

- Uses `entity.setAI(false)` instead of deleting entities - World feels "full" to players even during optimization - Only hard-clears items in Level 3 critical mode

Configuration

All settings are customizable via `config.yml`:

```yaml

Performance thresholds

thresholds: ram: moderate: 80.0 critical: 92.0 tps: moderate: 18.0 critical: 15.0

Distance settings

distances: view: min: 4 max: 16 simulation: min: 4 max: 12

Optimization settings

optimization: check_interval_ticks: 200 # 10 seconds chunk_unload_delay_minutes: 5 ground_item_clear_minutes: 2 ```
