⚡ OptimizerX — The Ultimate Overdrive Performance Solution

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, primitive-backed custom data structures like BlockKey and ChunkKey, it tracks redstone and hopper activity with absolute precision and a near-zero memory footprint.

Whether you run a heavy Towny, Factions, or massive Survival server, OptimizerX dynamically monitors your hardware resources and steps in with aggressive limits when your server needs it most—without breaking the core vanilla gameplay experience.


🚀 Key Features & Aggressive Modes


💻 Commands & Permissions

All commands require the optimizerx.admin permission node.

Command Description
/ox clean Triggers a deep, lag-free smart purge on loaded chunks and safely invokes GC if required.
/ox usage Displays real-time free RAM ratios and the exact number of active chunks loaded.
/ox force Activates extreme Overdrive Mode to aggressively handle heavy server stress.
/ox gc Forces the JVM garbage collector to run immediately with a before/after RAM comparison.
/ox purge Aggressively clears ground items older than 60s, freezes distant mob AIs, and forces GC.
/ox chunks <radius> Asynchronously pre-loads chunks within a block radius centered at world spawn.
/ox chunks status Displays the live progress, percentage complete, and processed counts of the preloader.
/ox chunks cancel Aborts the active chunk preloader task and clears the saved disk progress file.
/ox chunks resume Resumes a previously stopped chunk preloader seamlessly from its last saved disk state.
