+## 2025-03-20 - Database Connection Pooling
+**Learning:** `streamrip/db.py` creates a new `sqlite3.connect` for *every single database operation* (`contains`, `add`, `all`). In bulk operations like resolving a playlist with hundreds of tracks, this introduces significant overhead.
+**Action:** Use a single persistent connection per database instance instead of creating a new one on every method call.
