Load test and performance test

Load and performance tests are essential

The correct use of load and performance tests makes an important contribution to a high-performance system in productive operation. But even after the go-live, it is important not to lose sight of the load and performance behavior of the application. Increasing user numbers, changes in user behavior, growing databases, etc. can gradually worsen performance and user experience. The reaction under peak load, e.g. in the course of a marketing campaign, must also be safeguarded in order to prevent expensive advertising campaigns from fizzling out or even damaging the image.

Performance is crucial to success

IT applications or websites with poor performance are at a clear competitive disadvantage. Internet users and customers today expect response times of less than two seconds: Every additional second leads to a loss of sales. But fast systems also enable companies to work more efficiently and better when using internal IT applications. Application performance and scalability are underestimated in almost all IT projects. Timely planned and correctly executed load and performance tests prevent nasty surprises at go-live.

Non-functional requirements, e.g. the maximum response time in certain use cases, but also the scalability of the architecture must be addressed and systematically checked as early as the development phase. Omissions or wrong decisions made here can no longer be corrected at the end of development, or only with immense effort.

• You are about to commission a new application?
  We support you in defining non-functional requirements regarding the performance, efficiency and scalability.

• You are developing a new application and want to prevent future performance bottlenecks?
  We support you developing your load and performance activities.

• You are facing the market launch of a new application and want to avoid a worst case scenario?
  We guarantee beforehand your going live with suitable measures.

• You want to be sure that your application also performs well during productive operation?
  We design a suitable monitoring for you and assist you during the implementation.

• You have performance problems regarding productive operation?
  We help you to identify the bottlenecks.

The load test measures the system behavior at increasing system load (e.g. several users are concurrently accessing the application) in order to find out the maximum load that can be born.

A stress test checks the system behavior under overload, e.g. by operating with excessive data volume or improper operation. Thus, aspects such as robustness (correct operation in the case of errors) and error tolerance (consistent performance despite wrong entries) are tested.
