A beginner's review on IBM Rational Performance Tester
Pros
- Data Parameterisation/ Data Correlation is made simpler compared to its competitors
- Distributed Load Testing is easier to set up
- Performance metric gathering while a test is in progress
- Th look and Feel really helps a beginner to understand and work with.
Cons
- Memory utilization could have been improved.(Eats up system's RAM)! It may crash if a test is conducted with the heavy load if adequate RAM is not available in the VM/host machine.
- Licensing could have been made simpler. IBM's licensing method is difficult to follow.
- Support for protocols other than HTTP. Not really up to the current trend.
Return on Investment
- Accuracy in metrics, thus improving system's performance
- Costs less compared to competitor like HP LoadRunner
- Helped the team of beginners learn things quickly
Alternatives Considered
JMeter and HP LoadRunner
Other Software Used
Dynatrace Application Monitoring, JMeter, Anaconda
