Note that on weaker computers the process of testing access speeds to different DNS can take up to an hour. Just run the downloaded file and press the 'Start Benchmark' button. That's exactly what namebench is looking for. However, there are other reliable DNS servers that can provide higher response rates in individual cases. The fastest and most secure servers are usually offered by Google and Yandex, so most ISPs use them by default. In general, DNS response is one of the most important factors that affect the speed of access to sites and other web resources. The sooner the request is sent and processed by the server, the sooner the page will be loaded. When entering the URL, the DNS server determines the IP that corresponds to it and sends the user to the desired site. For those who do not know, every web resource on the Internet has its own IP address. Not sure how? Then view this Google page, replacing its server IP addresses with the ones that namebench recommends.Namebench is a free program that allows you to increase the speed of 'surfing' in the network by selecting the fastest DNS-servers. You'll still have to change your DNS server settings manually, unfortunately. Go make a coffee or something, give the program the 10 or 15 minutes it needs, then come back and admire the finished report: detailed charts and graphs that tell you exactly how fast each server is, and recommend the two that you need to use. You should stop using your PC while the benchmark is running, just to ensure that you don't skew the results. Click 'Start Benchmark' and namebench will extract 200 recent URLs from your browser history, then query several DNS servers for each one. To get started, launch the program and choose your most commonly used browser in the Benchmark Data Source list. There are plenty of public alternatives around, and namebench can help you find out whether any of these would improve your surfing speeds. You don't have to use the DNS server provided by your ISP, though.

DNS lookups normally take a fraction of a second, but slow servers might take 3, 4, 5 seconds or more to return any information for some sites, and that can quickly become very frustrating.

But another possibility is that your DNS server (the computer that translates a domain like into an IP address like 209.85.229.147) is just slow. The delay might be down to the remote site. It happens all the time: you type a URL into your browser address bar, hit enter, and there's a long pause before anything happens.
