How to Reduce RAM Usage on a Minecraft Server Using Put A Plug In It

Why Servers Benefit Most

Servers run for days or weeks without restarting, so memory leaks compound far worse than in singleplayer. Put A Plug In It is built to address exactly this — it cleans up entity brain memory, drowned navigation data, and biome temperature caches that would otherwise grow unbounded on a busy server.

Server-Side Setup Steps

1. Install the mod on the server. It works across multiple loaders and versions, so check that your server's loader is supported.

2. Install it on clients too if your players connect with modded clients — some fixes (like crosshair target and hit result reset) are client-side.

3. Restart the server after installation. The leak fixes activate on startup.

4. Watch your server's memory graph over the next few days. You should see a flatter curve instead of the usual sawtooth climb toward an out-of-memory crash.

5. If you run other memory mods, let Put A Plug In It handle the overlapping features. It is designed to integrate rather than fight them.

Tuning Tips

• Do not stack multiple mods that all patch the same entity cleanup routines. Pick one primary handler.
• The huge screenshot buffer free-on-failure fix matters less on a dedicated server but helps if you take screenshots in singleplayer.
• Combine this with a reasonable view distance and entity cap for the best results.
