Determine the exact performance of a local and remote DNS nameserver. DNS Benchmark performs a detailed analysis and comparison of the operational performance and reliability of any set of up to 200 DNS nameservers (sometimes also called resolvers) at once. When the Benchmark is started in its default configuration, it identifies all DNS nameservers the user's system is currently configured to use and adds them to its built-in list of publicly available "alternative" nameservers.

Each DNS nameserver in the benchmark list is carefully "characterized" to determine its suitability for use as a DNS resolver. This characterization includes testing each nameserver for its "redirection" behavior: whether it returns an error for a bad domain request, or redirects a user's web browser to a commercial marketing-oriented page. While such behavior may be acceptable to some users, others may find this objectionable.

DNS Benchmark bundled with a list of all popular public DNS servers and automatically includes the DNS servers that are being used by host system. In addition host also has the option of manually adding any DNS server benchmark.

After you run the small program just click on Run Benchmark. It will automatically test all the name servers present in the list for performance. It also offers a helpful summary and list of recommendations based on the result of the benchmark.

DNS Benchmark Feature List:
The Executable Environment:
1. Compatible with all versions of Windows from Windows 95 through Windows 7.
2. Compatible with Wine (Windows emulation) running on Linux and Macintosh.
3. Hand-coded in 100% pure assembly language for highest precision and smallest size: 154 kbytes.
4. Installation-free - nothing to install - just run the small executable file.
5. (Doesn't change anything or mess-up your system.)
6. Lightweight (single packet) automatic and/or manual version checking.
7. Task Scheduler compatible for non-UI non-interactive background operation.
8. Optional, automatic results logging for fully unattended operation.
9. Comprehensive error return codes to support full automation.

Primary Benchmark Features:
1. For each of up to 200 DNS nameservers, using the Internet's most popular top-50 domain names, independently measures, charts, statistically analyzes, reports (and optionally exports):
2. Optionally verifies whether nameservers provide DNS security (DNSSEC) record authentication.
3. When using a list of (provided) DNSSEC-signed domains, benchmarks DNSSEC authentication performance.
4. Graphs and compares all four benchmark parameters with easy-to-read bar chart.
5. On-the-fly hierarchical sorting of performance results by cached (default) or uncached performance.
6. (Sorting is "hierarchical" because cached is sorted first, followed by uncached, then dotcom.)
7. Auto-scaled bar chart that can be manually overridden for chart-to-chart comparison.
8. Pop-up value "inspector" (left click in nameserver list) displays precise values on bar chart.
9. Detailed tabular result report for non-graphical detailed reporting.
10. Full detailed, locale-aware (internationalized), CSV results export.
11. Automatic logging to CSV file for long-term background results monitoring and collection.
12. Simultaneously compares the performance and reliability of up to 200 DNS nameservers.
13. Determines nameserver network name (reverse DNS), ownership, operational status.
14. Determines whether nameservers intercept and redirect bad domain names.
15. Comprehensive, heuristic "Conclusions" generation summarizes all results and suggests useful system changes, if any, in easily readable English.
16. All results are analyzed for statistical significance with a 95% confidence threshold.
17. Bottom of tabular data page contains built-in quick-reference "reminder" help.

Additional Power-User & Convenience Features:
1. The built-in top-50 domains list is user-replaceable to allow more or less accurate (and statistically significant) operation, and for support of DNSSEC record authentication. (More domains takes longer to run.)
2. .INI files containing sets and subsets of nameservers to benchmark can be added, removed, and saved.
3. Special "dnsbench.ini" is auto-loaded, if present, to always override built-in nameserver list.
4. (This supports the use of customizable personal nameserver lists for special applications.)
5. At startup, tests for the presence of, and deliberately "triggers", any outbound-blocking personal firewalls to allow Internet access exceptions to be provided before testing begins.
6. Internet connectivity aware - verifies unimpeded Internet connectivity before testing and gracefully handles possible loss of Internet connectivity during testing.
7. Bar chart results can be copied to the system clipboard or saved in BMP or compressed PNG format for storage or sharing.
8. Built-in self-screen capture to BMP or compressed PNG file.
9. All benchmark pages and tabs can be copied to the system clipboard or saved to files as text, rich-text, or images as appropriate.
