Performance

The server runs Paper 1.21.4 with 20 plugins, 11 datapacks, and 3 resource packs — all managed through Pterodactyl hosting. To keep things running smoothly with all of that loaded, several performance plugins work behind the scenes to reduce lag.

Here's what each one does and how it might affect your gameplay.

StackMob (v5.10.4)

StackMob merges nearby mobs of the same type into a single "stacked" entity. Instead of 30 individual cows, you'll see one cow with a number above its head.

How It Works

  1. When mobs of the same type are within 10 blocks of each other, they merge into a stack.
  2. Stacks can grow up to a maximum of 30 mobs.
  3. The stacked mob displays the count above its head (e.g., "x24").
  4. When you kill a stacked mob, one mob is removed from the stack and the appropriate drops appear.

What's Excluded

Not all mobs get stacked. The following are excluded to prevent gameplay issues:

  • Villagers — stacking would break trading and pathfinding
  • Water mobs (fish, dolphins, axolotls) — stacking would look unnatural in oceans
  • Raiders (pillagers, ravagers, etc.) — raids need individual mobs for mechanics to work

XP from Stacked Mobs

Killing stacked mobs gives a modified XP amount:

XP Multiplier

Each additional mob in the stack contributes 0.5x to 0.8x of the normal XP. So a stack of 10 zombies doesn't give 10x the XP — it gives roughly 5x to 8x instead.

This is a deliberate balance choice. Stacked mob farms are still good XP sources, but they're not infinite XP exploits.

Do drops multiply normally?

Yes. Each mob in the stack drops its normal loot when killed. A stack of 30 zombies killed one at a time will give 30 sets of zombie drops. Killing with sweeping edge or area damage may kill multiple from the stack at once.

Clumps (v5.0)

Clumps groups nearby XP orbs into a single larger orb. Instead of dozens of tiny orbs flying at you, one orb appears and is collected instantly.

How It Works

  • XP orbs that spawn close together are merged into one.
  • The merged orb contains the full combined XP value.
  • Collection is instant — no waiting for orbs to drift toward you.

Tip

You'll notice this most at mob farms and furnaces. Instead of a shower of green orbs causing lag, you get clean, instant XP collection.

VillagerLobotomy (v1.13.3)

VillagerLobotomy disables the AI of villagers that are confined in trading halls or similar setups. Trading still works — the villager just stops pathfinding, panicking, and consuming server resources.

How It Works

  • Villagers in minecarts or boats are automatically lobotomized (AI disabled).
  • Lobotomized villagers still display trades and can be traded with normally.
  • Their schedules, gossip, and pathfinding are turned off to save performance.

Manual Control

You can force or prevent lobotomy on specific villagers using name tags:

Name Tag Controls

  • Name a villager "nobrain" to force-lobotomize it regardless of its situation.
  • Name a villager "alwaysbrain" to prevent lobotomy, keeping its full AI active even in a minecart.
Does lobotomy affect breeding?

Lobotomized villagers will not breed, gossip, or restock on their own. If you need a villager to breed or restock naturally, keep it out of a minecart/boat, or name it "alwaysbrain".

Do lobotomized villagers restock trades?

This depends on the configuration. If your villager's trades are locked and not restocking, try ensuring it has access to its workstation, or use the "alwaysbrain" name tag to restore full AI.

Orebfuscator (v5.5.7)

Orebfuscator is the server's anti-X-ray system. It prevents cheaters using X-ray texture packs or mods from seeing ore locations through walls.

How It Works

  1. The server modifies network packets before sending chunk data to your client.
  2. Ores and valuable blocks that you can't see (behind stone) are disguised as stone in the data sent to you.
  3. As you get closer to the blocks (within line of sight), the server reveals the real block.

No Client Impact

This is entirely server-side. You don't need to install or configure anything. Ores appear normally as you mine toward them — you'll never notice Orebfuscator during normal gameplay.

Why do I sometimes see blocks change as I approach?

That's Orebfuscator revealing real blocks as you get within range. It's most noticeable if you mine quickly or if you have high render distance. The blocks "pop in" as the server deobfuscates them.

Let Me Despawn

In vanilla Minecraft, mobs that have picked up items (even a single rotten flesh) become persistent and never despawn. Over time, this leads to thousands of invisible mobs cluttering the world and eating server resources.

How It Works

  • Mobs that picked up items are allowed to despawn again after their normal despawn timer.
  • Named mobs (with name tags) are always protected and will never despawn.
  • This prevents the slow buildup of persistent garbage mobs over the server's lifetime.

Note

If you want to keep a mob permanently, name it with a name tag. Named mobs are fully protected from both vanilla despawning and this plugin. Mobs with picked-up items that you haven't named are considered temporary.
