It probably doesn't apply to most of our readers/customers at work, but at home it sure might.
I saw an article saying that Google released some public DNS servers that are supposed to be super fast, which will speed up your web browsing experience.
Now, here’s an article that mentions a tool called “Namebench” which will search for the fastest DNS servers based on your network and location and will list them for you (if that be Google’s or someone else’s’).

I ran it at home and it showed my fastest DNS servers were one from Level 3 and one from Comodo Secure DNS (faster than Comcasts’ DNS servers). So I changed my Linksys router at home to use these 2 DNS servers on the WAN link and also setup my DHCP scope to use my router plus these DNS servers. The results are noticeable-- browsing is way faster and I’d recommend checking it out!
