What are performance testing tools? Before an application can be deployed, it should ideally be tested under different operating conditions to make sure it can perform as expected. To do this, software testing professionals use performance testing tools (sometimes just called “testing tools”) to isolate and identify potential client, network, and server bottlenecks that might affect how an application will behave in production.
Some performance test products are commercial....
It doesn't really concern me. Licensing is on a yearly basis.
The pricing is a little bit on the higher side, although it is really good.
