ServerCore Mod is designed to optimize server performance, making gameplay smoother and reducing lag. This mod implements patches and optimizations to minimize random lag spikes.

It reduces lag caused by large trading halls and limits the number of mobs of the same type in a specific area to prevent overcrowding.
