Performance Benefits

Performance Benefits: "As web pages become more complex, referencing resources from numerous domains, DNS lookups can become a significant bottleneck in the browsing experience. Whenever a client needs to query a DNS resolver over the network, the latency introduced can be significant, depending on the proximity and number of nameservers the resolver has to query (more than 2 is rare, but it can happen). As an example, the following screen shot shows the timings reported by the Page Speed web performance measurement tool."
