- batch_operations.rs: replace join_all with buffer_unordered, Arc<str> for shared IDs, remove redundant clones and dead Semaphore - folder_db_repository.rs: use COUNT(*) OVER() for single-query pagination; UPDATE RETURNING for rename/move (eliminates extra SELECTs) - folder_service.rs: remove StorageTransaction wrapper from rename/move — direct repo call (4→2 and 5→3 queries) - search_service.rs: replace sort_by(to_lowercase) with sort_by_cached_key (N vs 2·N·log₂N allocations) - image_transcode_service.rs: dynamic rayon pool sizing via available_parallelism() instead of hardcoded 2 threads - Remove dead transactions module (zero consumers after folder_service refactor)
