About this Mod

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.

Is HP: HariPlayer compatible with forge?

HP: HariPlayer officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with HP: HariPlayer – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if HP: HariPlayer consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
