Lazy DataFixerUpper’s Possibilities
It is also LazyDFU. This is the Forge port of the Fabric version.
It won’t generate the rules to migrate the data from previous releases of MC to newer ones until it’s required.
Additionally, it will not reset DFU. It’s safe. However, it will act more carefully than the normal situation.
You will not often spend your time converting data for every update of the game. Therefore, DFU rule compilation will come later while MC has started and is running.
So, you can witness lag spikes once LazyDFU causes the game to compile migration rules. Nevertheless, once the process ends, there is no performance penalty.
You can compare that to other mods like Cadmium, Smooth Boot, or anything that clears DFU.
Lazy DataFixerUpper(LazyDFU) [FORGE] is an available server utility mod. It needs you to download and install Minecraft Forge before you launch it!
