MCOptimizer

MCOptimizer — Smart Server-Side Lag Mitigation

MCOptimizer is a lightweight yet highly effective server-side utility designed to eliminate the root causes of server lag in Minecraft. Instead of heavy mods that completely rewrite game logic, MCOptimizer selectively and smoothly unburdens the server CPU from the most common lag culprits: excessive item drops, frozen entity AI, stuck projectiles, and cascading fluid updates.

Perfect for both vanilla servers and heavy modpacks featuring complex technical or magical mods.

⚡ Key Features & Modules:

🧹 SmartItemCleaner

Prevents massive TPS drops caused by endless item drops from automated farms or uncollected loot.

• Automatically tracks, merges, and safely clears item groupings to significantly lower entity ticking and rendering overhead.The /ecoperform command can cleanse the world of garbage.

🏹 ArrowLagCleaner

Projectiles shot by skeletons or players that get stuck in blocks continue to tick constantly, dragging down server performance.

• This module scans for stuck arrows, checks their NBT tags, and gently purges them from the world, freeing up vital ticking cycles.

💤 LazyEntityAI

Mobs that are far away from any player shouldn't consume valuable server resources by calculating complex pathfinding routes.

• Dynamically optimizes and throttles the AI behavior of passive and hostile entities based on their distance to the nearest player. Mobs in semi-active chunks will no longer cause TPS spikes!

🌊 FluidStuckOptimizer

Massive water or lava flows, along with glitchy infinite sources, often cause micro-stutters due to continuous block updates.

• Forces cascading fluid updates to "settle" and optimizes ticking states around players, instantly stopping chunk-update-related freezes.

⚙️ Technical Highlights:

• 100% Server-Side: Install this mod only on the server. Players can connect seamlessly without needing to install it on their clients.
• Smart Ticking: Heavy checks and cleanups are hooked into player ticks rather than a rigid, heavy global timer. This ensures a smooth mitigation process without the sudden lag spikes common in old-school cleaners.
• High Compatibility: Works flawlessly alongside other chunk-loading or performance-enhancing mods.
