To keep our server running smoothly and lag-free for everyone, we use an automated anti-lag system. This guide explains what players should know about entity limits, redstone machines, farms, and more.

---

Too many mobs, hoppers, or redstone contraptions in one area can slow the server down for everyone. The anti-lag system helps manage this by automatically controlling or removing excess entities and machinery.

---

Entities are limited **per chunk** or **grouped chunks** (e.g., a 3x3 chunk area).

| Entity Group | Limit per Area | Notes |

| ----------------------------------- | -------------- | ------------------------------------------ |

| Animals (pigs, cows, sheep, etc.) | 40 | Applies to grouped area |

| Monsters (zombies, skeletons, etc.) | 40 | Includes hostile mobs |

| Example: Chickens | 20 | Even if animals aren't hostile, they count |

| Example: Sheep | 50 | Higher limit allowed |

---

* Hopper transfer rates are **dynamically slowed** if overused.

* If you use many hoppers in a small area, they’ll **work slower** to reduce lag.

* This **breaks redstone contraptions** that rely on specific timing.

| Setting | Value | Meaning |

| -------------- | -------------------------- | -------------------------------- |

| Default Rate | 8 ticks | Normal speed |

| Max Slow Rate | 40 ticks | Slowed to 1 item every 2 seconds |

| Adjust Trigger | Every 30 items transferred | |

💡 **Tip:** Keep hopper setups small and efficient!

---

Every **30 seconds**, the server checks areas near players for excessive mobs.

* **No warning** is given before cleanup.

* Players with `mfm.cleaninform` permission will be notified of cleanup results.

---

To stop lag machines, we limit certain block types **per chunk**.

| Block Type | Max Per Chunk |

| -------------- | ------------- |

🛑 **Note:** Piston activity across chunks is monitored even more strictly.

---

To reduce lag and potential abuse, some mob spawning is restricted:

| Rule | Description |

| ------------------------------- | ------------------------------------------- |

| Over-limit mobs | **Will be removed** without warning |

| Natural Mob Spawn Reasons | Controlled (see technical section below) |

---

To avoid accidental removal of important things, the following are **safe** during cleanups:

✅ Armor stands with items

✅ Item frames with items

✅ Tamed animals

✅ Named animals

✅ Saddled animals

✅ Baby animals

✅ Entities that have picked up items

---

Some areas or specific coordinates may be exempt from entity checks. These are mostly for admin or event use and should not be relied upon.

---

The server restricts certain spawn reasons, including:

(Only allowed with permissions)

---

Each entity type has its own limit. Some examples:

| Entity | Max Allowed |

| ------------ | ----------- |

| Blaze | 30 |

| Axolotls | 20 |

| Bees | 20 |

| Warden | 10 |

| Sheep | 50 |

➡️ Limits vary by mob. Admins may change these based on server needs.

---

* Spread farms across chunks, don't stack everything in one spot.

* Avoid building mega hopper chains or laggy redstone loops.
