Cavisson NetStorm
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, and runs on Linux, web and self-hosted platforms with an on-premise deployment model. Test scenarios can be based on user arrival rate or concurrent user count; Cavisson says NetStorm can simulate millions of concurrent users. WAN simulation can model packet delay, loss, reordering and duplication. Tests can include page reload and click-away behavior, or use access log replay to recreate production scenarios. Client-side reports cover DOM load, on-load, page load and rendering time, caching metrics, page scores and waterfall comparisons. Diagnostics include metric correlation, capacity or behavioral alerts, and runtime comparisons against a baseline. Supported technologies include HTTP/1.1, HTTP/2, HTTP/3, WebSocket, SOAP and REST. The script converter migrates existing test scripts while retaining predefined functions. A Jenkins plugin is listed for CI/CD. Pricing is available on request; a free trial signup is offered, with no duration stated.
