| CEO at Xcelliti | 4.0 | No summary available |
| Testing Tool Expert at a insurance company with 10,001+ employees | 4.0 | I appreciate the strong technical support and IBM integrations, but I find its component development poor, making it hard to scale and set up. Its complexity means understanding needs is crucial. |
| Senior Test Architect at a tech services company with 11-50 employees | 3.5 | I value this tool for its comprehensive protocol support, excellent scalability, and integrated performance test management, enabling agile development. Despite the time-consuming initial setup, its cloud load generation and features are highly beneficial. |
| Architect Software Test Engineer at MAS Global Consulting | 3.5 | I find its code extension valuable if you have Java skills, enabling effective load testing. However, it suffers from stability issues due to Eclipse, is a resource-eater, and has average customer support. |
| Associate - Projects at a tech services company with 10,001+ employees | 3.5 | I find its automatic correlation, Java integration, and detailed performance reports valuable. While cheaper than LoadRunner and good for web applications, it needs better protocol support. |
| Java Developer + Workflow/Process Automation Developer with 501-1,000 employees | I mainly used it for load and stress tests, finding its data pools and logging valuable for scaling our application's performance. Customer and technical support were good, though initial setup was complex for a novice. | |
| Solutions Architect at a tech services company with 501-1,000 employees | I've used this for 8 years, valuing its Java customization, editor, and server metrics; it even caught a critical CPU error. But, customer service sometimes incorrectly claims "works as designed" and deployment issues have occurred. | |
| Quality Assurance Software Testing Lead at a government with 1,001-5,000 employees | 3.5 | I appreciate this tool's ease for non-programmers and its responsive support. It offers significant ROI by eliminating vendor costs, unlike our previous expensive HP solution, despite HP being marginally better overall. |
