My arrival on the client site was after the product had already been chosen by the client. I did not participate in the selection/evaluation process that had occurred.

We previously used HP Performance Center. We changed due to HP overcharging for additional protocols needed for testing. IBM Rational Performance Tester does not charge any additional fees.

I did not switch solutions. Our company had this solution; it was the available product to deliver the services.

We previously used HP LoadRunner and switched because the license is cheaper.

We chose this product because the client had a full contract with IBM for software services.

I have used a variety of the tools that are available.

Previously, I used JMeter, because if we are talking about the open version JMeter is nearly perfect in usability and reliability side. But, since the organization changed, I needed the more powerful tools.

JMeter was used previously, but we found it limited in terms of protocol support, scalability, and lack of support for the entire test process i.e., analysis and reporting.

I hadn't used a similar solution before.
