💬Fantastic Performance Saver

Fantastic Performance Saver is a lightweight server-side performance protection mod for Hytale servers.

This mod helps reduce unnecessary server load by automatically adjusting performance-related settings when the server is under pressure or when no players are online.

It is designed for live multiplayer servers where stability, TPS protection and smooth gameplay are more important than forcing the server to run at full load all the time.

Features

Adaptive View Radius

The mod can automatically reduce the view radius when server performance drops.

This helps lower the amount of chunks and world data the server has to process while the TPS is unstable.

Default values:

AdaptiveViewRadius:
  MinViewRadiusChunks: 6
  MaxViewRadiusChunks: 12
  DefaultViewRadiusChunks: 12

Explanation:

DefaultViewRadiusChunks: 12 The normal view radius when the server is running fine.
MaxViewRadiusChunks: 12 The highest view radius the mod will restore.
MinViewRadiusChunks: 6 The lowest view radius the mod can reduce to when performance protection is needed.

This keeps the server playable while reducing load during lag spikes.

Idle TPS Saver

When no players are online, the server does not need to run at full active TPS.

The mod can lower the world TPS while the server is empty and restore it when players come back.

Default values:

IdleTpsSaver:
  IdleTps: 5
  ActiveTps: 20

Explanation:

IdleTps: 5 Used when no players are online. This saves server resources.
ActiveTps: 20 Used when players are online. This restores normal gameplay performance.

This is useful for public servers that stay online 24/7.

Memory Protection

The mod can monitor memory usage and optionally trigger system garbage collection.

Default value:

Memory:
  UseSystemGc: false

Why is this set to false by default?

Calling system garbage collection manually can sometimes cause short freezes or lag spikes, especially on live servers.

For most servers, Java's own memory management is better and smoother. That is why UseSystemGc is disabled by default.

Recommended setting for live servers:

UseSystemGc: false

Only enable this if you know what you are doing and want to test it on your own server setup.

Player Notifications

The mod can notify players in chat when it changes performance settings.

Default value:

General:
  NotifyPlayers: false

Why is this set to false by default?

When this option is enabled, players may receive chat messages whenever the mod changes something.

Examples:

View radius was reduced
Server entered saver mode
TPS was adjusted
Performance protection was activated

On live servers, this can annoy players or make the server feel unstable, even when the mod is just doing its job in the background.

Recommended setting for live servers:

NotifyPlayers: false

Admins can still check the server status with commands and server logs.

Commands

/fpsaver status

Shows the current performance saver status.

/fpsaver reload

Reloads the configuration.

/fpsaver gc

Manually triggers garbage collection.

Permissions

fantasticperformancesaver.use

Allows basic command usage.

fantasticperformancesaver.admin

Allows admin commands like reload and manual GC.

fantasticperformancesaver.notify

Allows receiving admin performance notifications if enabled.
