@@ -30,4 +30,5 @@ Intentional differences from the Java behavior:
 - `GET /actuator/sessions` without `?username=` lists all sessions (Java rejects it).
 - `/api/v1/books/{bookId}/next` and `/previous` break `numberSort` ties by book id; Java's tie-handling is unstable — see [Next/previous navigation](/server/enhancements/next-previous).
 - Memory is bounded regardless of CPU cores: 16 MiB SQLite page-cache budget per database (`cache_size` pragma overrides), and `malloc` arenas capped at 2 on Linux/glibc (`MALLOC_ARENA_MAX` overrides; `1` saves more on tiny boxes but serializes C-side allocation).
+- SQL statements that run 500 ms or longer are logged at WARN with their text (log target `komga_db::slow_query`); lock waits count toward the time, so lock-starved writers show up too. The Java version has no slow-query log.
 - Collection/read list covers: adaptive collage of up to 4 member covers (1 full, 2 side-by-side, 3 = 1 tall + 2 stacked, 4 = 2×2) on a blurred, dimmed blowup of the first cover (neutral gray when no cover is available); Java renders a fixed 2×2 grid on black, cycling members.
