PerformanceX

v1.1.91 - Performance improvements across multiple modules

Performance Fixes

• Pathfinding Limiter - state-change-only NMS: setNoAi was called via NMS reflection on every living entity every sweep (default: every 20 ticks) regardless of whether the AI state needed to change. Now uses a transition-tracking map and only calls NMS when a mob's AI state actually changes. onDisable() also now restores only the mobs it actually disabled instead of scanning all world entities.

• Villager Optimizer - state-change-only AI calls: setAI() + reflective setAware() were called on every villager every sweep regardless of state. Same fix applied - only fires on transitions. restoreAll() now iterates the tracking map instead of all world entities.

Bug Fixes

• Mob Stacker - player-renamed stacked mobs now protected: If a player used a nametag on a mob that was already stacked (size > 1), the previous check getStackSize() <= 1 would fail, leaving the named mob vulnerable to further stacking. Now distinguishes player names from generated stack labels by checking the name format.

• Mob Stacker - stackSizes map memory leak: The in-memory stack size map only cleaned up entries on EntityDeathEvent. Mobs removed by /kill, entity limiters, mob clear, or chunk unloads would leave entries forever. Added a periodic pruning task (every 10 min) that removes entries for entities that no longer exist.

• Auto Backup - save_wait_seconds cap + log message: save_wait_seconds is now capped at 30 (config validation) to prevent accidentally blocking the async backup thread for an unreasonable duration. A log message is now printed so admins can see why backup startup has a brief wait.
