The utility of an application depends on its performance. Often, performance bottlenecks are identified late in a project and are costly to fix. We understand our customers’ performance concerns, and have the skills and expertise to benchmark and fine tune your applications.

Regardless of the lifecycle of your applications, Opus can provide performance testing services to optimize your systems’ performance. Our testing services can help you determine the reliability, stability and performance of your applications.

Our ranges of tests include Qualitative and Quantitative Performance Tests, Load Tests, Stress Tests, Endurance Tests and Spike Tests

• Qualitative and Quantitative Performance Tests: We can do quantitative tests in a lab, like measuring the response time or the number of MIPS (millions of instructions per second) at which a system functions. We can also evaluate qualitative attributes such as reliability, scalability and interoperability.
• Load Test: This is the simplest form of performance testing. A load test is usually conducted to understand the behavior of the application under a specific expected load. This load can be the expected concurrent number of users on the application performing a specific number of transactions within the set duration. This test will give out the response times of all the important business-critical transactions. If the database, application server, etc are also monitored, then this simple test can itself point towards the bottleneck in the application.
• Stress Test: This testing is normally used to break the application. The number of users is steadily added to the application, which is run until it breaks down. This kind of test is done to determine how robust the application is in times of extreme load. It helps application administrators to determine if the application performs if the load is well above what is generally expected.
• Endurance Test: This test is usually done to determine if the application can sustain the continuous expected load. Generally, this test is done to determine if there are any memory leaks in the application.
• Spike Test: This is done by spiking the number of users and understanding the behavior of the application, whether it will be able to handle dramatic changes in load or stop functioning.
