TELEPORT OPTIMIZER

Teleport Optimizer is a server-side Fabric mod for Minecraft 1.20.1 designed to completely eliminate teleport-related MSPT spikes.

πŸš€ What This Mod Does

Teleport Optimizer replaces Minecraft’s default teleport handling with a high-performance teleport pipeline that:

βœ… 1. Preloads chunks BEFORE the teleport happens

No more stutters when a player arrives in an unloaded area.
Chunks are intelligently requested, sorted, and prepared ahead of time.

βœ… 2. Batches teleports to avoid lag spikes

If many players teleport at once (events, RTP spam, respawns), the mod processes them in controlled micro-batches to eliminate any server freeze.

βœ… 3. Async & parallel scheduling

Using CompletableFutures and a lightweight executor, nearly all heavy work is offloaded away from the main server thread.

βœ… 4. Mixins that patch vanilla teleport bottlenecks

The mod intercepts and replaces slow teleport logic inside ServerPlayerEntity, removing the synchronous stall that normally occurs.


βš™οΈ Core Features

πŸ”Ή ChunkPreloader

  • Preloads destination chunks around the target location

  • Ensures chunk readiness before teleport

  • Uses smart radii & ordering to preload only what’s necessary

  • Avoids “teleport into void” delays

πŸ”Ή TeleportBatcher

  • Queues teleports instead of forcing them instantly

  • Smooths out load spikes

  • Dramatically improves MSPT stability during heavy player activity

πŸ”Ή Teleport Metrics

  • Optional lightweight profiling

  • Tracks average & worst-case teleport performance

  • Helps server admins debug chunk-loading hotspots

πŸ”Ή Admin Command

/teleportoptimizer reload
— Reloads config and recalculates batching rules on the fly.
