Counts for /tags, /performers, /studios and /favorites were computed live per-request by aggregating scene_tags / scene_performers with an EXISTS to playback_sources. As the catalog grew to ~1.7M scenes (6.3M scene_tags) this ran ~4.3s for /tags?order=popular (x2 incl. the total count) and ~950ms for the default /scenes count, making those screens load in several seconds. - migration 0019: add scene_count (+ DESC index) to tags/performers/studios - background job _job_refresh_taxonomy_counts (every 3h) recomputes the counts in one UPDATE..FROM each (IS DISTINCT FROM to skip unchanged rows) - /tags, /performers, /studios scenes path now read the column + ORDER BY the indexed scene_count; for_movies paths keep live aggregation (small tables) - favorites read denormalized scene_count instead of a grouped EXISTS aggregate - /scenes default count: 10-min in-process TTL cache (header is approximate) Measured: /tags?order=popular&per_page=500 ~8s -> 66ms incl. serialization.
