Lithium vs ServerCore

Lithium is a free Minecraft mod that optimizes game systems to improve performance. Its work covers physics, mob AI, block ticking, world generation, chunk loading, explosions and redstone wire calculations. It runs on both client and server, but does not need to be installed on both sides. The project says it does not alter game mechanics or visuals and is compatible with most other mods. Lithium supports Fabric and NeoForge. Stable optimizations are active after installation without extra configuration; players can disable individual patches to address bugs or mod compatibility issues, though changes take effect only after restarting the game. The project directs downloads through Modrinth or CurseForge. For multiplayer server administrators, it says improved tick times can let hardware support more loaded entities, chunks and players. In single-player, it optimizes Minecraft’s internal server and may free processor capacity for frame rates and responsiveness. Automated bleeding-edge builds may include unfinished code, bugs or crashes, and are intended for people comfortable debugging software.

ServerCore is a free, self-hosted Minecraft mod focused on server performance and lag-spike reduction. It runs on dedicated servers and in singleplayer, with Modrinth compatibility for Fabric, Forge, and NeoForge. Entity Activation Range reduces the entities processed by the server. Dynamic checks can adjust chunk-tick distance, view distance, simulation distance, and mobcaps according to tick time and configuration. Administrators can set spawn rates and mobcaps per spawn group, with optional rules for reinforcements, spawners, and nether-portal random ticks. Breeding Caps limit same-type breeding within a radius, while chunk-ticking-distance narrows the range for mob spawning and random ticks. Commands include reload, settings, status, mobcaps, and statistics. Configuration files are config.yml and optimizations.yml in config/servercore. Changes that alter vanilla behavior are disabled by default.
