 ## Notes
 
-- **sqlite3 Performance**: The sqlite3 driver shows lower performance in synchronous-style benchmarks because it's inherently asynchronous.
+- **sqlite3 Performance**: The sqlite3 driver shows lower performance in synchronous-style benchmarks because it's inherently asynchronous. Note: sqlite3 is [deprecated and unmaintained](https://github.com/TryGhost/node-sqlite3/pull/1844) since December 2025.
 - **Memory Testing**: Always run memory benchmarks with `--expose-gc` for accurate garbage collection control.
 - **Real-world Performance**: These benchmarks test specific patterns. Real application performance depends on your specific use case.
