What Cavisson NetStorm is
Cavisson NetStorm is an application performance testing and capacity-analysis solution that estimates Client Perceived Response Time. It supports load, stress, browser-based, distributed-load and API testing on Linux, web and self-hosted platforms, with on-premise deployment. Scenarios can use user-arrival rates or concurrent-user counts, and Cavisson says NetStorm can simulate millions of concurrent users. WAN simulation introduces packet delay, loss, reordering and duplication, while access-log replay recreates production traffic. User behavior models include page reloads and click-away actions. Browser reports cover DOM, on-load, page-load and rendering times, caching metrics, page scores and waterfall comparisons. Diagnostics provide metric correlation, behavioral or capacity alerts and baseline runtime comparisons. Supported protocols include HTTP/1.1, HTTP/2, HTTP/3, WebSocket, SOAP and REST. A script converter retains predefined functions, and Jenkins CI/CD components support automated test execution. Pricing is on request, with a free trial and 24×7 support.
