How to use energy saving lightbulbs

A question – since energy saving lightbulbs are compact fluorescents, presumably they consume more energy when powering up than they do when actually lit. So in a room which is often vacant, but visited frequently – like the toilets in an office – is it better to leave them on all day or to switch them off when you leave the room? When we first installed such lights in our office, we were told to leave them on all day, but that was fifteen years ago. Has the technology moved on since then, or did we just stop paying attention to it?
