The Yes, but... part of my answer emphasizes awareness. How are the network engineers going to know it's worth the (minor) effort of creating properly-sized queues?

There are two fronts to attack:

- Manufacturers - This video is a start on getting their customers to use these responsiveness test tools and call the support lines.

- Hardware (especially router) reviewers - It kills me that there is radio silence whenever I ask a reviewer if they have ever measured latency/responsiveness.  (BTW: Has anyone heard from Ben Moskowitz from Consumer Reports? We had a very encouraging phone call about a year ago, and they were going to get back to us...)
