That sounds completely crazy. The DNS servers are only used to resolve an IP and they in no way impact actual bandwidth. The only thing they can impact is resolution speed. Once the IP is obtained the DNS servers don't matter at all. Can you take a video or screenshots? Are you sure your tests are identical in all other respects? It's.... just.... nuts.....
But the point is that resolution speed ultimately throttles bandwidth by creating "dead air". A reasonable page such as CNN.COM takes many DNS lookups. Bypassing the RR DNS servers seems to be making pages load a couple of seconds faster. That couple of seconds is saved bandwidth. Put a 50ms delay into each DNS lookup and the average user might view one or two fewer pages per hour. That adds up.
