Lag Free
What does the mod do?
Lag Free aims to reduce lag on Minecraft servers making the experience better for players and make hosting easier for server owners. The mod also adds a layer of protection from lag machines made from snowballs, arrows and ender pearls.
How does it work?
In the config, located at world/serverconfig/lag_free-config.toml, you can specify a timer in seconds that defines every how often a clear lag happens.
By default, lag clears delete every item on the ground. In the config, you can also optionally choose to make it remove every Minecart and Armor Stand, but these may make farms and certain redstone mechanics involving them unusable.
