HP: HariPlayer
A server-side optimization mod that improves multiplayer performance through async chunk loading, spatial entity tracking, and network packet efficiency
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.

HP: HariPlayer server crashes on startup – what to do?
Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.
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.
