Server Performance - Smooth Chunk Save

Source-provided project description. FreeMinecraftMods keeps creator credit and adds separate compatibility and decision guidance below.

Project overview

Saves chunks continuously over time, reducing server lag and preventing lagspikes from saving too many chunks at once. Vanilla 1.18: Server with 3 players. Chunk saving takes ~ 11% of the server tick. With smooth chunk saving: 0.3% of the server tick Depending on some varying factors this can give you up to 10% more server side performance effectively, with no downsides. Server here also applies to playing in single-player worlds, as those are running an integrated server. Requires Cupboard dependency to be installed in newer versions Set the time interval after which a chunk is saved Set how many chunks can get unloaded at once Enable debug logging Only Required on server side(Integrated/Dedicated) No known incompatibilities, should work fine with any mod. If you enjoy this mod consider supporting the development, any support is greatly appreciated. The development is an unpaid free-time activity, so any support helps being able to spend more time on it. You can support me on Patreon or just spreading the word around.

FreeMinecraftMods decision guide

This mod is most relevant to players looking for Map and Information, Server Utility on Fabric, NeoForge, Forge. Treat those labels as discovery hints, then verify the exact file and dependency list on the official project page.

The source record was updated on Jul 5, 2026, which is a recent freshness signal. A recent date does not guarantee support for every loader or Minecraft version, so still inspect the current file list.

What to verify before choosing a file

• Confirm that the file is published by the credited creator on the linked official source.
• Match the Minecraft version exactly instead of relying only on a broad category label.
• Read dependencies, incompatibilities, and changelog notes before updating an existing instance.
• Match the loader or server platform and its required version. Forge and NeoForge are not interchangeable.
• Back up worlds and configuration files before testing the project in a long-term save or public server.
