Optimizations

GriefDefender provides built-in control for nearly every action in your minecraft world. However, attempting to control too much can sometimes cause resource issues depending on your server load. The solution to this issue is to make use of built-in optimization configuration found in global.conf and by learning how to use blacklists.

Global Optimization config

Below is a snippet of the optimization settings you can find in GD's global.conf

Global Optimization Config

optimization {
        # Whether to process player claim tool actions async for performance. (Default: true)
        # Note: If you encounter any async thread issues, disable this setting.
        async-claim-tool-actions=true
        # Whether to process player claim visuals async for performance. (Default: true)
        # Note: If you encounter any async thread issues, disable this setting.
        async-player-claim-visuals=true

        block-item-drops=true
        # Controls the amount of time, in seconds, for the permission cache of all entity damage actions in world. If the cache is accessed before expiration then the time is reset.

        cache-entity-damage-expiration=5
        # Controls the amount of time, in seconds, for the permission lookup cache of all actions in world. If the cache is accessed before expiration then the time is reset.

        cache-permission-lookup-expiration=3
        # Controls the amount of time, in seconds, for the permission cache of all block physic changes in world. If the cache is accessed before expiration then the time is reset.

        # Controls whether player attacks against a monster are ignored.
        # Note: This does not include explosion damage.
        player-monster-damage=true

Below you will find user contributed configs for servers that have worked heavily on improving GD performance for their needs

IMPORTANT

⚠️ These settings are tweaked for individual servers and may not work on yours. It is HIGHLY recommended to test these configs before using them in production. ⚠️

Dino's Known Issues

- Water can grief claims from outside going in of region claims (removing water from the liquid flow blacklist flag will prevent that but keep in mind that active water flow has a big performance impact)
- Players can activate wooden pressure plates by dropping an item on them
- Players can shear other peoples sheep
- Players can leash entities in other people claims (mostly an issue if you use a plugin that leases villagers and other entities that is not possible with vanilla minecraft)
- Creepers can kill entities in claims
- Players can interact with item frames only when they interact with an item in hand (spin around the items)
