This update provides significant performance improvements for both image and scene duplicate searching: 1. Optimized the core Hamming distance algorithm in pkg/utils/phash.go: - Uses native CPU popcount instructions (math/bits) for bit counting. - Pre-calculates hash values to eliminate object allocations in the hot loop. - Halves the number of comparisons by leveraging the symmetry of the Hamming distance. - The loop is now several orders of magnitude faster and allocation-free. 2. Solved the N+1 database query bottleneck: - Replaced individual database lookups for each duplicate group with a single batched query for all duplicate IDs. - This optimization was applied to both Image and Scene repositories. 3. Simplified the SQL fast path for exact image matches to remove redundant table joins. |
