“A slow or outdated DNS server may result in slower web site connections. For my neighbor’s [slow browsing] Mac, I simply changed the DNS setting from the default to OpenDNS, one of a number of free global DNS servers (I also use EasyDNS, and the new Google Public DNS),” Wil Gomez reports for Mac360.
“Suddenly, Safari came alive. Web pages seemed to snap to the screen without the previous delay,” Gomez reports. “Could it be that simple? Apparently not all DNS servers are equal. After a bit of research we found a Mac utility which tracks down and tests DNS servers.”
“There are many, many DNS servers scattered over the internet. The default DNS from your internet service provider might not be the fastest one to use, depending on your location,” Gomez reports. “The utility namebench hunts down the fastest DNS server for your computer and location. It’ll take anywhere from five to 15 minutes, but when it’s done, it will list the faster DNS servers.”
