DNS Benchmark: Local And Remote DNS Nameserver Performance Benchmark


DNS Benchmark is a benchmark utility which is developed to analyze open DNS servers speed and other response-time related parameters to let you decide which DNS server should be used. According to the developer, it is built to check ‘How fast and reliable your ISP’s DNS server is, when compared to other open DNS servers’? It conducts several tests and generate a detailed report, which lets you do DNS server reliability and speed comparisons.

To start off with checking the fastest response, enable Sort Fastest First option (from left side) and click Run Benchmark to conduct a test. It may take some time to check all the listed DNS servers’ response-times.

After the test is finished, you can view response-time related parameters box by clicking the DNS name in the list. It carries information regarding three basic parameters which includes; Cached, Uncached, and DotCom. There are four tabs; Name, Owner, Status and Response Time to view all the information regarding the response time of listed DNS servers.
