## Summary - Replaces scan-based decay checking during world saves with an event-driven timer wheel scheduler - Removes virtual property checks from serialization hot path, achieving 6-8x faster world saves ## Changes ### DecayScheduler (new): - Timer wheel with 12 HashSet buckets (5-min intervals) + PriorityQueue for active processing - O(1) register/unregister vs O(n) scan of all items - Auto start/stop when items exist/empty - Configurable tick interval with jitter to prevent system synchronization ### Item.cs: - Added ScheduledDecayTime computed property - Added UpdateDecayRegistration() called from SetLastMoved(), property setters, AddItem()/RemoveItem() - Hooks in Visible, Movable, Spawner setters and Delete() ### World.cs: - Removed _decayQueue, EnqueueForDecay(), ProcessDecay() - ItemPersistence.Serialize() now tight loop without virtual calls ## Performance | Metric | Before | After | Improvement | |---------------|------------|-----------|-------------| | Items (230K) | 245K ticks | 34K ticks | 8x faster | | Mobiles (43K) | 56K ticks | 6K ticks | 9x faster | | Total | 302K ticks | 40K ticks | 7.5x faster | ## Configuration decay.maxItemsPerTick = 250 # Items processed per tick decay.tickInterval = 256ms # Base processing interval decay.bucketInterval = 5min # Timer wheel bucket size decay.jitterMaxMs = 25 # ±25ms tick jitter |
