Zefir's Optimizations

Zefir's Optimizations is a Fabric modification that implements parallel entity movement using Akka actors technology. The main goal of this mod is to move the processing of mob and armor stand movement out of the main game thread, which allows for gradual performance improvement on servers with multi-core processors.

The mod's operation is based on assigning each mob and armor stand its own actor. When it's time to process entity movement, the asynchronous tick manager sends a command to the corresponding Entity Actor to perform the work. The entity actor receives messages in its queue and processes them sequentially.

Some actions, such as dealing damage or picking up items, must be performed in the main thread for safety reasons. When an Entity Actor needs to perform one of these actions, it sends a message to the main thread actor, which then executes the work.

Currently, Entity Actor implements the tickMovement() and travel() methods from the LivingEntity and MobEntity classes (armor stands inherit them from LivingEntity).

For noticeable effect, you need a processor with at least 2 cores! The more cores, the better the performance.

Warning: The mod may work unstable and cause various problems with entities, world, and other game aspects. Use at your own risk!
