NetStorm can generate high load with a single machine. Its Runlogic feature is very useful to send load to cover each and every flow of the application. NetStorm gives the feasibility of generating load with multiple load arrival models helping components to be tested based on its usage. NetStorm has monitoring capabilities integrated into it to see the performance of components while the test is in the running phase. One more great functionality is the ability to control the load runtime by increasing or decreasing the virtual users or pausing the users to keep on repeating the transactions without exiting.

1. Load generation
2. Designing scripts
3. Recording scripts
4. Dynamic scenarios
5. Measuring system capacity
6. Identifying bottlenecks of an application.
7. The performance report after generating load and the comparison report analysis.
8. Advance APIs, which are supported with use cases like MQ  and TIBCO.
   

It is a very good technology to use. It is easy to understand the dashboard. The navigation is easy, user-friendly, etc. 

There are many features that no other tool on the market provides but I would recommend using the different comparison metrics, the different real-world scenario creation ability, and the support for different protocols.
