HariPlayer | View Distance & Network Engine

High-Performance Player & Chunk Management

What Is HariPlayer

HariPlayer stands for View Distance & Network Optimization Engine (based on VMP).

It optimizes how servers handle player connections, entity tracking, chunk loading, and network packets — reducing lag where it matters most.

More Players. Less Lag.

By reworking player-related systems from chunk loading to packet handling, HariPlayer allows servers to sustain higher player counts and larger view distances without choking.

Technical Architecture

Optimized for high-throughput multiplayer environments.

• Async Chunk Loading: Chunks load asynchronously on player login and during teleportation to prevent lag spikes
• Spatial Entity Tracking: Replaces brute-force distance checks with O(1) spatial indexing using AreaMap
• Network Efficiency: Eliminates redundant packet flush calls and supports multi-event-loop Netty threading
• No-Tick View Distance: Loads chunks visually without ticking them, reducing server load at large distances
• Packet Consolidation: Batches block update packets to reduce network overhead

Configuration

Located in config/vmp.properties.

• Entity Tracking: Toggle spatial indexing and staging area for entity lookups
• Async Loading: Enable/disable async chunk loading on login and commands
• Network: Configure multiple Netty event loops and packet priority system
• Chunk Send Rate: Control the target chunk send rate per player

Fork Information

HariPlayer is a fork of VMP by ishland.

Server-Side: Primary optimizations target dedicated servers. Client-side benefits from reduced network lag.
