NeoForge Minecraft Mods: Optimize TPS, FPS and RAM

Is your NeoForge Minecraft server suffering from lag, TPS drops, or memory issues? This detailed guide presents the best NeoForge-compatible optimization mods, tested up to version 1.21.x. We've selected the most effective solutions to radically transform your server's performance.

All listed mods have a compatible NeoForge or Forge version. For each mod, you'll find a direct download link, clear explanation of its purpose, and supported Minecraft versions. Installing several of these mods together eliminates lag spikes, maintains stable TPS, and provides a smooth gaming experience for all your players.

💡 Tip: If a mod isn't yet available for your Minecraft version, regularly check its CurseForge or Modrinth page. Developers frequently publish updates.

Server Optimization and TPS Mods

These mods act directly on the server core: mob AI, redstone circuits, terrain generation, entity management. Their main goal is to maintain TPS close to 20, even with many players, complex automatic farms, and massive constructions.

Server Mods Summary Table

Server Mods Details

Adaptive Performance Tweaks

Impact: Saves without freeze

C2ME (Concurrent Chunk Management Engine)

Download on CurseForge

Executes chunk generation, lighting, and heightmap construction in parallel. Exploration, which previously halved your TPS, becomes much more manageable. Still in alpha but very performant on multi-core processors.

Versions: NeoForge 1.21 (alpha)
Impact: Terrain generation up to 3x faster

Ksyxis

Download on CurseForge

Completely eliminates spawn chunks permanently held in memory, freeing several hundred MB of RAM and computation time each tick. An option allows keeping a reduced area if necessary.

Versions: NeoForge 1.21 → 1.8

Impact: Lighting system up to 50x faster

Get It Together, Drops!

Download on CurseForge

Automatically merges ground items upon appearance. Explosive quarries or massive farms no longer generate thousands of individual entities to process.
