DNS May Be Limiting Smartphone Speed
Back before one could save contacts on phones, we had to input phone numbers to call someone. Thankfully we have not had to do the same with the Internet as a site's domain name is translated to its IP address for us. Researchers at Northwestern University have recently found that the servers that perform that translation can have a significant impact on how quickly our smartphones perform when web surfing.
Domain Name Servers (DNS) are a crucial part of the Internet as without them one would have to keep track of the IP addresses for every site they visit. Like any piece of hardware though, a DNS can become bogged down with requests. The Northwestern researchers were curious if the particular DNS service a smartphone uses could influence its performance exploring the Internet. To their surprise, it not only had an impact, but a large one as well. When tested, some services improved performance by up to 150%, compared to the DNS service one's carrier uses.
To help users find the best DNS service, the researchers created the Namehelp app, which is currently available in the Google Play Store. While it may find a better DNS for your location and the sites you visit, you may not be able to achieve any of that improved performance, unless you have rooted your phone, as carriers lock down what DNS you use on their networks (Wi-Fi would be different though).
