[SW:TESB] So, a bunch of us crew members on the Executor were wondering how far Vader's power extends. The Admirals seem scared, but can Vader really kill everyone on the bridge or just one or two people at a time?

It would almost be preferable to have Vader kill everyone simultaneously. Unfortunately, in situations like this, he has a tendency to just seal the door behind him and go through everyone with a lightsaber. 

Is Vader powerful enough to break the trachea of each person in a room at once? Sure. But is it easier than stabbing them all? Does is send the right message to whomever has to clean up and spreads the rumors of the carnage following those who displeased Lord Vader?

Really, it comes down to his mood, why he's so pissed, who he is trying to punish and/or send a message to, and if he is in more of a stabby mood or a chokey mood. 

Edit: also it seems uncharacteristically wasteful for Vader to kill everyone on the bridge crew of his flag ship. They were chosen for that post due to competence. Frankly, the lower you are in the totem pole, the safer you are. He prefers to make examples of leaders, not peons.
