Lag and Listeners?

I'm working on a HUD/avatar combo, and its kinda script heavy. My question is this:
Is there a difference in the amount of lag a link_message generates, in contrast to a LlListen()? (In other words..is there more lag when sending messages to non-linked prims, rather then linked ones?)

Where both a listen and a link message make the sim have to check on the event, thus casue a wee bit of lag, the listen has the added problem of generating extra checks should there be any activity on the channel, even if from outside your object.

Use link messages when you can, and target them when you can. The fewer scripts you trigger for each message the easier it is on the sim.

Reserve listens for long distance communication.
