Our Solution

Abstracta conducted stress tests on the system, focusing on identifying performance deficiencies in the application. We installed the test software, created test scripts, executed test scenarios and analyzed the test results for changes.


Load testing: OpenSTA

Monitoring tools: Windows Performance Monitor, IBM iSeries Navigator, JMX and DbMon


During the stress test, we implemented changes and improvements to the application.

We were able to prove that, using the new infrastructure, the application could successfully handle the peak loads experienced during the weekly “rush hours”.

We then reconfigured the new equipment so as to obtain the optimal possible performance from the application.

We improved critical transaction response times in the three main test cases.

We managed to reduce the time to complete the product shipping process from 763 milliseconds to 432 milliseconds at 50% of the estimated maximum traffic load.

Across the board, test case response times were reduced by 46% on average.

Furthermore, our stress test results provided documentation and recommendations for additional application performance enhancements.
