Northwestern University researchers have found that public Domain Name System (DNS) services could slow down users' Internet connections, and have developed namehelp, a solution that could speed up Web performance by as much as 40 percent.

The Northwestern researchers, led by professor Fabian Bustamante, found that users' Web performance can suffer due to the hidden interaction of DNS with Content Delivery Networks (CDNs), which help performance by offering exact replicas of Web site content in computer servers around the world. The namehelp system runs personalized benchmarks in the background, from within users' computers, to determine their optimal DNS configuration and improve the Web experience by helping sites load faster.

The researchers also found that, for a user who is receiving less than optimal Web performance, namehelp automatically fixes it by interacting with DNS services and CDNs to ensure they get the content from the nearest possible copy.
