<\/span><\/h3>\n\n\n\nRecursive resolvers<\/strong> perform complete DNS resolution themselves, querying root servers, TLD servers, and authoritative nameservers. They offer full control but require more resources and have higher latency.<\/p>\n\n\n\nForwarding resolvers<\/strong> simply forward queries to upstream resolvers (like 1.1.1.1 or 8.8.8.8) and cache responses. They’re faster, simpler to configure, and leverage optimized public infrastructure. Most internal networks use forwarding resolvers.<\/p>\n\n\n\n<\/span>Can I use dnsperf to benchmark public resolvers?<\/strong><\/span><\/h3>\n\n\n\nYes, but your results will include your network latency and routing to their infrastructure. This is useful for comparing public resolvers from your location, but not for measuring your local resolver’s capacity. For internal testing, always use a local IP address (192.168.x.x, 10.x.x.x).<\/p>\n\n\n\n
<\/span>Why do results vary between test runs?<\/strong><\/span><\/h3>\n\n\n\nMain factors: cache state (cold vs warm cache causes 10-100\u00d7 difference), network conditions, server load, and time of day. For consistent results, run at least 3 iterations, discard outliers, and average the remaining results.<\/p>\n\n\n\n
\n\n\n\n8. Conclusion<\/h1>\n\n\n\n
dnsperf is an essential, battle-tested tool for evaluating DNS resolver performance. Whether you’re tuning a small home resolver or validating a large-scale DNS service, dnsperf helps you measure exactly how fast and reliable your DNS infrastructure is.<\/p>\n\n\n\n
With just a few commands, you can benchmark:<\/p>\n\n\n\n
\n- Maximum throughput
<\/li>\n\n\n\n - Latency under load
<\/li>\n\n\n\n - Query loss
<\/li>\n\n\n\n - Overall server health
<\/li>\n<\/ul>\n\n\n\nProperly configured DNS resolvers on modern hardware can handle enormous query loads. With Unbound in forwarding mode on decent server hardware, achieving 50,000-100,000 QPS is routine, far exceeding the requirements of most deployments.<\/p>","protected":false},"excerpt":{"rendered":"
