NoSpawnChunks

Table of Contents

This project is abandoned and its default file will likely not work with the most recent version of Minecraft. Whether this project is out of date or its author has marked it as abandoned, this project is no longer maintained.

NoSpawnChunks

What does it do?

Ever wished you could run more on less? Multiworlds taking up all your memory and noone visits them very often?

The solution is now simple: install this plugin! This plugin does one thing, and one thing only, prevents spawn chunks being loaded into memory for all worlds on the server.

What does this mean in practice?

It means you can run a 2 person server on as little as 32mb ram (including 8-10 lightweight plugins). It also means that the memory impact from having 10+ worlds enabled at once on your server is reduced to an absolute minimum.

How to install

There is no configuration, it is literally drag and drop. Just install the plugin, stop the server, and do a full restart; the plugin is now enabled, and you should notice a dramatic drop in memory footprint.

There are no known errors to using this plugin other than increased server performance ;)

Plugin conflicts

Not so much a conflict - but if you are trying to run in a low-memory situation, any plugin that force-loads chunks will ruin that for you.

Sounds a possibility.

I'll see if I can resolve incompatabilies - it shouldn't unload chunks from a world unless there's no players though.

I have v0.3 working on latest version of CB .. seems to work alittle to well .. I believe its stopping my BlockDoors mod from working correctly. It seems to stop the script from triggering my doors open. Also I think it messes with wireless redstone and/or solar redstone torches...

dono.. anyone with any ideas .. I m wondering if this is something to do with the Authors note: "plugin that force-loads chunks will ruin that for you" ?

This is an amazing plugin, even though the new version bugs out the older version works well.
