mongodb-perf-wrapper

Monkey-patches node-mongodb-native to capture query performance metrics. Wraps the mongodb driver so every operation (find, insert, update, remove) reports duration in microseconds via a callback. Unwraps cleanly. Version 0.1.3 (latest) – no updates since 2014, stable for its narrow use case. Lightweight with no runtime dependencies beyond mongodb itself. Not compatible with mongodb@3+ due to internal API changes.
