Measure the Performance and Capacity of Carrier-Grade DNS Servers Against a High Scale of DNS Queries
Internet functionality depends on DNS servers to process an enormous number of requests simultaneously. DNS Storm is a DNS server test tool that sends a continuous stream of DNS query types to measure DNS server performance under stress. Use DNS Storm to load test DNS servers to help determine points of failure and eliminate performance bottlenecks.
Stress Test DNS Servers at Scale
DNS Storm can generate up to 2 million DNS queries per second from up to a million different clients to find the breaking point of any DNS server.
Test DNS server performance by tracking how many queries are completed or lost and measuring the latency of query response times. DNS Storm supports more than a dozen DNS query types and tracks common DNS response codes.
BENEFITS
- Perform value-seeking DNS performance tests to find the maximum number of queries per second a server can handle
- Configure tests with valid and invalid queries to assess how the device will respond
- Scale testing by sending up to 2 million queries per second from 1 million emulated clients
- Avoid manual user entry with DNS Storm’s WebCrawler that auto populates a list of 500 thousand of the current most popular domains
- Induce cache misses and stress the DNS server to find the breaking point
- Capture statistics such as queries sent, queries lost, avg. packet size, min and max latency etc.
Evaluate DNS Server Real-World Responses
DNS Storm uses a web crawler to automatically populate and continuously update a catalog of half a million of the world’s most used domains. Accurately evaluate the server’s real-world response to both valid and invalid queries without the hassle of manual domain input.
Configure tests quickly and easily with DNS Storm’s modern, wizard-driven user interface or automate testing using RESTful API.
