# Minecraft | How to use Pre-Generate your World with Chunky

### Map pre-generation is critical to lag removal. Do it before you even touch your server files but you can also do this even if you have an existing world

1. Go and Install [Chunky Plugin](https://www.spigotmc.org/resources/chunky.81534/) to your server

2. Set a reasonable border distance and generate your map using the plugin commands.

**1,000 Blocks Wide is typically 1GB of Storage. So, if you set your world boarder to 5,000, it will take 5GB of your Storage**


3. The hours it will take depends on how many blocks you set the world boarder. 

4. It is best to do this when no one is playing on your server as it will make your server lag in the process of pre-generating since it is using too much hardware.
