About this project
What does No Lag add?

No Lag
Description
Stop common causes for lag on your Fabric server.
This mod aims to prevent common causes of lag by allowing you to limit the amount of projectile entities in an area, prevent someone from having too many ender pearls loaded, stagger mob ticks in an area with too many mobs, and stagger vehicle ticks in an area with too many vehicles.
This will stop people from making lag machines based on creating too many entities.
It will also stop people from using too much RAM or lagging a server out by loading too many chunks with ender pearls.
And the staggering of mob ticks allows for players to have thousands of mobs in an area, and only their mobs experience lag while the server TPS stays at 20.0
