This update provides additional performance improvements specifically targeted at large image libraries (e.g. 300k+ images): 1. Optimized the exact match SQL query for images: - Added filtering for zero/empty fingerprints to avoid massive false-positive groups. - Added a LIMIT of 1000 duplicate groups to prevent excessive memory consumption and serialization overhead. - Simplified the join structure to ensure better use of the database index. 2. Parallelized the Go comparison loop in pkg/utils/phash.go: - Utilizes all available CPU cores to perform Hamming distance calculations. - Uses a lock-free design to minimize synchronization overhead. - This makes non-zero distance searches significantly faster on multi-core systems. |
