Kind's Anchor Optimizer

Kind’s Anchor Optimizer

Smooths lag caused by respawn anchor explosions on Fabric servers.

Kind’s Anchor Optimizer is a server-side Fabric mod that prevents major TPS drops when many respawn anchors are detonated at once. Instead of letting every anchor explode in the same tick, explosions are spread over time to keep the server running smoothly—while still behaving like vanilla.

No balance changes. No gameplay changes. Just better performance.

Why Use This Mod?

Respawn anchors are one of the biggest causes of lag spikes on PvP, anarchy, and stress-heavy servers.

Kind’s Anchor Optimizer helps by:

Reducing TPS drops during mass anchor detonations

Keeping explosions fair and vanilla-feeling

Improving stability during heavy combat or griefing

Working server-side only (client install is optional)

With Mod on 70Ms

Without Mod on 70Ms

What It Does

Detects respawn anchor explosions in the Overworld and End

Removes the anchor block immediately

Queues explosions instead of detonating them all at once

Processes a limited number of explosions per tick

Automatically adjusts based on player count

The result is smoother gameplay even under extreme anchor usage.
