HariMT | Async Entity Engine

High-Performance Asynchronous Entity Ticking for Minecraft 1.20.1

What Is HariMT

HariMT is a performance and stability overhaul for Entity Ticking.

It allows the server to process entities in parallel, ensuring that a large number of mobs or items does not bring the server to a halt.

Designed for Modern Modpacks.

HariMT includes built-in compatibility for popular optimization mods like Lithium, Radium, and VMP.

Technical Architecture

HariMT moves the entity ticking pipeline off the main thread.

• Parallel Processing: Entity logic is executed across multiple worker threads
• Main Thread Offloading: Drastically reduces the load on the main server thread
• Safety System: Includes checks to ensure thread safety for entity operations
• Lower MSPT: Reduces the time taken to process each tick

This architectural change allows the server to scale with CPU cores.

Configuration

Configurable via config/harimt.toml.

• paraMax: Controls the maximum number of threads (-1 for Auto)
• enableAsyncSpawn: Experimental feature to handle entity spawning asynchronously
