Load & Performance Testing

Ensure the effective deployment of your systems and the reliability of ongoing operations by leveraging TestPro's expertise in application Load, Performance and Stress testing.

System performance under load and stress is an area of significant risk for any project. To minimise this risk you need to have the expertise to plan, design and execute a performance test using the best available tools. TestPro has broad experience and specialist skills in this area, providing tools, hardware and the skills to deliver a load test in your project with a useful and cost-effective outcome.

• Tools: Rational, HP (Mercury) , Segue, Compuware, Scapa, Open Source etc
• Fixed Price tests
• Infrastructure diagnosis
• Remote site load testing (including international)
• LAN/WAN performance and response times
• If required, supply test hardware

Using automated testing tools, you can deliver a repeatable and established series of outcomes. With automated testing tools the tests are:

• Proactive
• Not labour intensive
• Highly repeatable
• Accurate performance times measured
• Scalable - increasing test user numbers accurately
• Tuning can be measured
• Can run across existing WAN networks for measurements
• Simulate business usage patterns  
• Able to vary the data access patterns of the real users

Clearly when simulating system behaviour with a load test, the objective is to use the test to obtain a level of information about the performance of the system. The test will then place your team in a position to clearly understand key issues related to your system;

• How many online users can your system support?
• What response times will the end users see?
• What kind of load will the new application create?
• What impact does geographical location make?
• Where should tuning be carried out, what key parameters?
• Is the hardware sizing configuration appropriate?
• Where additional funding should be allocated for infrastructure?
• Are there architecture bottlenecks?

The Load Testing Project is divided into three phases;

1. Planning & Environment,

2. Preparation,

3. Execution & Reports.

Each phase has a milestone for evaluation and continuation into the next phase. These distinct phases provide an opportunity to evaluate progress against the roadmap/project plan and to ensure the project can continue unimpeded.

We have deep expereince in building performance test environments. We are also aware of defining the differences between the test environment and the production environment. Even though it may appear to be “the same” it is often different due to minor changes in configuration, version, or dependencies.

Estimating the variances due to these differences, and/or identifying and quantifying the key differences is an important part of the test process.

Hardware Capability

TestPro has the ability to support your organization with all the load test hardware required as a part of the solution. This hardware has a nominal coverage cost associated with it, that is significantly less than the hire/purchase cost of this hardware.

In addition, TestPro can facilitate access to a full range of hardware that can be used for full-scale load tests off-site in a controlled environment. Thus load testing of applications already in production can be covered.

Bottlenecks

TestPro has a significant expertise in this area of load and stress testing. Understanding that a test has many possible outcomes is critical to understanding where bottlenecks may be found.

It is TestPro's experience that whilst additional hardware can support more load, by altering software application components and configurations greater performance improvements are often found.
