📦 Adaptive Performance Tweaks

Adaptive Performance Tweaks, also known as APTweaks, helps Minecraft servers stay responsive under load by automatically adjusting selected server-side behavior.

It can reduce entity pressure, adapt spawn limits, optimize items and XP orbs, adjust selected game rules, protect players during login, and scale view or simulation distance based on server load.

Important: 12.x is a complete rewrite

APTweaks 12.x is no longer a bundle of separate modules.

Starting with 12.x, Adaptive Performance Tweaks is a single all-in-one mod. The old Core, Spawn, Game Rules, Items, Player, View Distance, Simulation Distance, and Monitoring features are now included in one unified mod.

If you are upgrading from 11.x, remove all old APTweaks files before installing 12.x.

Remove:

• adaptive-performance-tweaks-core
• adaptive-performance-tweaks-spawn
• adaptive-performance-tweaks-gamerules
• adaptive-performance-tweaks-items
• adaptive-performance-tweaks-player
• the old bundle file

Do not install 12.x together with any 11.x module. Mixing both generations can cause conflicts or startup errors.

Status ✅

12.x

Alpha.

Use 12.x for new servers, new modpacks, Fabric support, NeoForge support, or if you want the new all-in-one architecture.

Please report issues on GitHub.

11.x Classic Modular Edition

Stable LTS.

The old 11.x module system is still available and can continue to be used for existing Forge modpacks.

If your current 11.x setup works well, you do not need to upgrade immediately.

Which version should I use?

Installing 12.x

1. Remove all installed 11.x APTweaks files.
2. Download the 12.x file for your Minecraft version and mod loader.
3. Place it in your mods/ folder.
4. Start the server.
5. Review the generated config files.

Config files are generated in:

config/adaptive_performance_tweaks/

Spawn presets are stored in:

config/adaptive_performance_tweaks/spawn_presets/

Default limits are tuned for small servers with about 4 players. For larger servers, increase per_player_max and per_world_max in the spawn preset JSON files.

11.x Classic Modular Edition

The 11.x version uses separate modules. The Core module is required by all other 11.x modules.

Classic module pages:

• Core Module
• Spawn Module
• Game Rules Module
• Items Module
• Player Module

The old bundle file was only a meta package for launchers. It did not include the modules itself. For manual 11.x installs, install the individual modules listed above.
