? What is ServerOptimizer?

ServerOptimizer is a lightweight, high-performance Paper/Spigot plugin built for Minecraft 1.20.4+ that surgically targets the three most common causes of server lag:

All heavy computation runs asynchronously — the main thread stays at a clean 20 TPS.

✨ Features

⚙️ Entity Optimizer

• ? Periodic async entity scans across all loaded chunks
• ✂️ Culls excess entities when a chunk exceeds your configured cap
• ? Item merging — stacks nearby dropped items instead of deleting them
• ?️ Named entity protection — entities with name tags are never removed
• ? Spawn-time gating — cancels spawns before the entity is created (cheaper than culling)
• ? Per-world enable/disable support

?️ Chunk Optimizer

• ⏱️ Idle chunk unloading — automatically requests unload after configurable inactivity
• ? Player-radius tracking — keeps only chunks near active players loaded
• ? Async load rate limiting — prevents chunk-generation spam from overwhelming the server
• ? Uses WeakHashMap so unloaded chunk references are garbage-collected automatically

? Hopper Optimizer

• ? Configurable hopper tick rate — slow down hoppers from vanilla 8-tick to your preference
• ? Lazy mode — skips hoppers with empty source inventories entirely
• ? Per-hopper transfer rate tracked with ConcurrentHashMap
• ?️ Auto-purges stale hopper entries every 5 minutes — zero memory leaks

?️ Plugin Compatibility

• ✅ WorldGuard — entity listener uses HIGH priority, after WorldGuard's region checks
• ✅ EssentialsX — softdepend declared, no hard conflicts
• ✅ All listeners use ignoreCancelled = true to skip already-processed events

? Developer Quality

• ? Hot-reload via /sopt reload — no server restart needed
• ? Thread-safe throughout (ConcurrentHashMap, WeakHashMap, AtomicInteger)
• ? Full config.yml with comments on every setting
• ? Tab-completion on all commands

  keep-loaded-radius: 4           # Chunks to keep around each player

# ─── Hopper Optimization ───────────────────────────
hopper-optimizer:
  enabled: true
  hopper-tick-rate: 16            # 8 = vanilla, 16 = recommended, 40 = aggressive

? Installation

1. Download ServerOptimizer-1.0.0.jar
2. Drop it into your /plugins/ folder
3. Start or restart your server
4. Edit plugins/ServerOptimizer/config.yml
5. Run /sopt reload to apply changes

⚠️ Requires Paper 1.20.4+ — Spigot is supported but Paper unlocks async chunk APIs and better scheduling.

? Performance Architecture

Main Thread (20 TPS — never blocked)
│
├── EntityListener        → Cancels over-limit spawns instantly (O(1) map lookup)
├── HopperListener        → Throttles transfers via timestamp gate (O(1))
└── ChunkListener         → Records load times into WeakHashMap (O(1))

Async Thread Pool (Paper Scheduler)
│
├── Entity Scan Task      → Iterates chunks, builds removal list
├── Chunk Cleanup Task    → Finds idle chunks, requests unload on main thread
└── Hopper Cleanup Task   → Purges stale ConcurrentHashMap entries

Main Thread (dispatched back)
│
├── entity.remove()       → Thread-safe mutation
└── world.unloadChunkRequest() → Thread-safe mutation

Rule: Read async. Write sync. Never mutate Bukkit world state off the main thread.

? Benchmark Impact

Tested on a Paper 1.20.4 server with 20 players, 800+ entities, and 200 active hoppers.
