or want to experiment with different browsers. You may want to tweak the rest if you're outside the U.S. If you're concerned about network censorship, check the third box, and if you want to help the developers, check the last box. Namebench is a free app that checks to see whether your current settings are optimized and, if not, which free option is best for you. Not sure how? Then view this Google page, replacing its server IP addresses with the ones that namebench recommends.Most people use the default DNS settings provided by their ISP, and while they are usually sufficient for most purposes, there are plenty of free options out there, like OpenDNS and Google DNS. 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.
