Right. I intended that to be a heads-up in both directions: it is not simply a library convenience function, so one needs to think about when to use it. In particular, it's possible that overuse of sendfile() in the wrong circumstances will create additional system load instead of reducing it.

Can you say more about this? I assume that sending static images back and forth is a good fit for sendfile(). -- _jsn
