If you are using the express.logger() middleware, you can easily add a :response-time token. See http://www.senchalabs.org/connect/middleware-logger.html for documentation.

Otherwise, use the responseTime middleware and do something like

 console.log(res.getHeader("X-Response-Time"))

in your own middleware.
