On Demand Performance Testing - Accelerate Performance
Overview
Predicting performance capability of online solutions is essential to succeed in this competitive market. System Canada's Performance testing center of excellence(PTCOE) team has rich experience in performance engineering tools from vendors like Mercury, Rational, Segue, Open Source Tools (Open STA), etc. We focus on analysis, monitoring, identifying bottle necks and proving recommendations, thus providing an end-to-end performance solution for the complete application.
System Canada as an Independent Testing Services provider offers the following performance testing services to manage your risk with developing or deploying business critical systems. The team will help in determining the scope, complexity and size of the load, and the test architecture used for test execution.
In Load test, we measure server response times to verify if the application can sustain expected maximum number of concurrent users and expected maximum size of the database.
In Stress test, we measure server response times at varying loads starting from low load (low number of concurrent users), medium load (average number of concurrent users) through high load (expected maximum number of concurrent users through highest possible number of concurrent users until unacceptable levels of response times are experienced) to validate application's stability and validity. Response times are also measured while varying the size of the databases in similar manner.
In Capacity test, we test to determine the maximum number of concurrent users an application can manage without compromising response time.

Services
System Canada operates a Create-Run-Transfer Policy to ensure the customer is able to understand and reuse the Performance Test Suite repeatedly.
Application Component Testing:
Performance should be considered before the first line of code is ever written. System Canada provides Enterprise Application Services, which will help your development staff, avoid the common performance pitfalls when designing J2EE or Windows based applications. Once the code is at a a point where components or areas of code can be extracted and tested, performance testing should begin. System Canada uses a variety of tools to test various "pieces" of your application before the final product is complete. Testing the scalability of COM components, Enterprise Java Beans (EJB's), or web services directly through SOAP calls would be examples of this. Finding performance issues at this stage will save you money and time. By finding most of the performance issues during the development phase, you eliminate time on the back end of the project where time to market dates are critical.
Performance Benchmarking :
Benchmarking provides a model of how the system reacts to an individual Business Processes. Controlled levels of users will be applied to the system and certain performance parameters will be recorded to build the model. This information can then be used as a comparison if changes are made to the infrastructure.
Performance Diagnostics Testing :
If the system is not performing as it should, a set of tests will be designed to identify what is causing the bottleneck.
Performance Tuning Testing :
A set of tests will be designed to identify the optimum configuration for each of the core elements to ensure the maximum performance from the system is reached.
Soak and Reliability Testing :
Soak and Reliability tests will be executed over a prolonged period (usually up to 72 hours) to identify if any of the servers have memory leaks, memory de-allocation issues, the databases to be used are of the correct size, and the system is stable over prolonged periods of time.
Load Testing :
Tests will be executed loading the system with typical daily patterns. This will provide a list of system specifications under a controlled load such as Application Response Time, Bandwidth used, hits per second on the system, Transaction per second carried out by the system.
Stress/Scalability/Capacity Testing :
A set of tests that will identify the maximum number of concurrent users or transactions the system is able to process before the degradation in performance becomes unacceptable.
Spike and Synchronization Testing :
Tests the performance characteristics of the system when all the users are synchronized (Logon is most common).
Failover and Resilience Testing :
Tests to identify how the network, hardware, software, and database elements react when certain components are removed from the system.
Bandwidth Verification :
This will confirm the bandwidth of the pipeline on your site into the application is able to deal with the number of users.
Application Performance Monitoring :
24-7 monitoring of business critical applications post deployment enables identification of potential system failure before users do, preventing down time and loss of revenue. Enforce SLAs and receive warning alerts through continuous performance monitoring from real user perspective.
