It should last 18 seconds, yes. Most swarming bards will get a set of JBoots, because that is a good, stable run speed that doesn't change. It's a lot harder to swarm if every level your speed changed dramatically.
You could be experiencing lag? When you have 100 mobs all getting dotted at the same time, that's a lot of information to bog down your game. Have you considered this? Perhaps try a smaller kite and see if you are still getting the same issues...
