OptimizerX — The Ultimate Overdrive Performance Solution
Say goodbye to lag! High-performance optimization engine designed for heavy-loaded servers (Towny, Factions, Survival).

What is OptimizerX?
OptimizerX is a next-generation, aggressive performance optimizer built from the ground up to eliminate server lag, micro-stutters, and high RAM usage. By utilizing ultra-lightweight custom data structures like BlockKey and ChunkKey, it tracks redstone and hopper activity with absolute precision and zero memory leaks.
⚡ KEY FEATURES & AGGRESSIVE MODES
- ── Overdrive Mode (/ox force): Instantly pushes the plugin into emergency limits. Limits mob spawns to absolute essentials per chunk to save your TPS during critical lag spikes.
- ── Custom Key Architecture (BlockKey & ChunkKey): Uses highly optimized, primitive-backed custom objects instead of heavy Bukkit locations to store cache data. This ensures absolute thread-safety and a near-zero memory footprint.
- ── Smart Hopper & Redstone Limiter: Puts empty hoppers into a 5-second deep sleep and blocks lag machines by capping redstone ticks dynamically before they can choke the main thread.
- ── Asynchronous Map Pre-Loading (WarmupManager): Safely pre-loads your world spawn radius on startup asynchronously. Players won't experience chunk-generation lag when exploring!
- ── Dynamic View Distance (AFK Optimizer): Automatically detects AFK players and slashes their render distance down to 2 chunks, instantly freeing up huge amounts of network and CPU bandwidth.
- ── Intelligent Entity AI Throttling: If no players are nearby (within 10 blocks), Villager and Mob AIs are fully frozen. No wasted CPU cycles on hidden entities!
- ── Next-Gen Item Stacking: Merges dropped items up to 256 in a single stack with smooth custom neon holograms, lowering entity count massively.
- ── Hardware Auto-Tune: Automatically detects low-end hardware (low cores/RAM) and safely optimizes server.properties on the fly.
- /ox clean - Triggers a deep, lag-free smart purge on loaded chunks and safely calls garbage collection if needed. (Permission: optimizerx.admin)
- /ox usage - Displays real-time free RAM ratio and exactly how many chunks are currently loaded. (Permission: optimizerx.admin)
- /ox force - Activates the extreme Overdrive Mode to handle intense server stress. (Permission: optimizerx.admin)
- /ox gc - Forces the JVM garbage collector to run immediately and displays a before/after RAM comparison. (Permission: optimizerx.admin)
- /ox purge - Aggressively removes ground items older than 60 seconds and freezes the AI of all mobs that are far from players, then triggers GC. (Permission: optimizerx.admin)
- /ox chunks <radius> - Pre-loads chunks in a given block radius centered at world spawn in the background. Recommended to run before opening the server to players. (Permission: optimizerx.admin)
- /ox chunks status - Displays the current progress of the chunk preloader, including percentage complete and how many chunks have been processed. (Permission: optimizerx.admin)
- /ox chunks cancel - Stops the running chunk preloader and deletes the saved progress file. (Permission: optimizerx.admin)
- /ox chunks resume - Resumes a previously cancelled chunk preloader from where it left off. Progress is saved to disk so it survives server restarts. (Permission: optimizerx.admin)
Highly customizable, lightweight, and pre-configured out of the box for peak performance.
