About this project
What does HE: HariEntity add?
HariMultiThread | Async Entity Processing
Massively Parallel Entity Ticking & Spawning
What Is HariMultiThread
HariMultiThread is a multi-threaded entity processing engine (based on Async) that parallelizes entity ticking across all available CPU cores.
More Entities. Same TPS.
By distributing entity updates across a thread pool, HariMultiThread eliminates the single biggest bottleneck on entity-heavy servers — the main thread.
Technical Architecture
Designed for safe, scalable parallel entity processing.
- Parallel Entity Ticking: Entities are batched and processed concurrently across all CPU cores
- Async Mob Spawning: Natural mob spawning calculations run in parallel with the main tick
- Thread-Safe Synchronization: Critical entities (TNT, items, projectiles) are always processed on the main thread
- Explosion Processing: Dedicated thread pool for explosion calculations independent of entity ticking
- Dynamic Thread Pool: Automatically scales to use all available processors
Configuration
Located in config/async.toml.
- Thread Count: Maximum parallel threads (default: all available processors)
- Async Spawn: Toggle asynchronous entity spawning
- Synchronized Entities: Configure which entities must tick on the main thread
- In-game Commands:
/async configand/async statsfor runtime management
Safety & Compatibility
Not all entities can be safely parallelized.
- Always Synchronized: Projectiles, minecarts, boats, players, falling blocks, and shulkers
- Configurable: TNT, items, experience orbs, creepers, withers, and more can be toggled
- Mod Compatibility: Special handling for Harium, HariPlayer, and HariChunk integration
Fork Information
HariMultiThread is a fork of Async.
Experimental: Parallel entity processing may cause issues with some mods. Test thoroughly.
