**Chunky Plugin:**\
Pre-generating your world

A vital step in lag removal is pre-generating the world. This should be done before anything else. The best way to do this is with the [Chunky plugin](https://www.spigotmc.org/resources/chunky.81534/). All you have to do is install the plugin and run the following commands: /chunky radius 5000 followed by /chunky start.

This will pre-generate a 5,000 block radius around your world spawn. The server will lag heavily while the process is running, but once it is done your performance will improve dramatically. You can increase the radius as much as you like, but we recommend keeping it under 20,000 blocks. Any larger and you could possibly create more lag than you would be preventing.\
\
**Spark Plugin**:\
To install spark, just need to download the latest spark **.jar** file from [downloads page](https://spark.lucko.me/download) and place in the server `mods` or `plugins` folder.

spark will load the next time your server (re)starts.

You will be able to control spark with the `/spark` command.\

**Optional Plugins:**\
[**RoseStacker**](https://www.spigotmc.org/resources/rosestacker.82729/) (This plugin is perfect for servers that wish to alleviate common sources of lag, whilst also gaining access to features that improve the functionality and feel of the server.)
