We call it question of capability to adopt applications for ever-changing, fast pacing requirements of daily business, driven both by customers and employees. And there is only one way to learn what they are experiencing: to test applications just as they do.

Beograd as one of the most important banks in development of Serbian economy. Challenge Hypo Alpe-Adria–Bank a.d. Beograd needed to implement their all new front end system that should be deployed throughout all branches in Serbia. New system needed to support daily business of all branches in the country and it needed to be capable of handling large amount of simultaneous online users. Mission critical for the Bank was to have a strong, robust and reliable application that can cope well with great workload on a daily bases. The Bank needed to test the bandwidth of their system before it went live for daily usage. PSTech has provided the Bank with an effective and reliable solution.

PSTech Solution

By using LoadXpert performance testing tool, PSTech developed a solution implementing a robust test methodology supplied by LoadXpert tool, that supports complex usage scenarios and data processing, secure protocols, distributed server farm integrated with sophisticated infrastructure. That solution was able to successfully generate application load on demand by emulating workload of real life bank tellers and managers with a virtual user technology implemented in LoadXpert tool. After several rounds of testing, critical issues were discovered that needed extra attention, which in the end resulted with a greatly improved application response time and increased capacity to handle hundreds of users. Along with metric analysis of the application response under load, LoadXpert has also pinpointed bottleneck areas within application and its test bed that needed to be improved before going live. Information like that was very valuable since it unveils possible issues before they happen in the real world.


Our execution in engagement resulted in:

  • Average page response time reduced by 30%
  • Workload throughput increased by 40%
  • Dramatically decreased percentage of functional errors during high load, by 10 times
  • Increased supported number of users by 30%
  • Increased workload capacity (requests per second) by 250%

Customer Quote:

“The implementation of new frond end system was of crucial importance for future development of our bank. We wanted to make sure that all aspects of the delivered solution are functioning according to ambitious specifications. In order to do this we had two options. Our first option was to buy expensive test tools and to make huge investments in human resources in terms of new recruitments and trainings. The other option was to outsource performance, stress and load testing. Since we are financial institution and not IT company, we decided to go with the second option, but not only because we wanted to avoid huge investments in something that is not part of our core business, but also because of expert know-how that we expected from our outsourcing partner. We decided to go with PSTech and they showed level of professionalism and expertise much beyond our expectations. With help of PSTech we improved all of our critical parameters. During the project, they were not only performing tests, they were also consulting us by proposing solutions for improvement. For the future projects of this kind PSTech will be first support to think of.”
