[emaillocker id=”1873″]
[/emaillocker]
Background
- An eLearning Portal was to be launched within a few weeks. It was a ‘mission critical project’ for the customer- SP (service provider) who is involved in providing eLearning to universities with large base of students
- The portal functionality involves
– Online examination
– Multimedia rendering
– Learning based on course content
- Performance of the portal was a critical factor due to projected reach
- System architecture was evolutionary
About the Portal
- Portal was developed using open source tools
- Performance criteria not defined in the beginning and hence was not considered during the design
- Functionalities and GUI was evolving
- Expected Load – Around 100,000 simultaneous users
Our Role
- To define typical User Scenarios to cover a cross-section of portal functionality
- Defining Performance profiling across different user loads
- Setting up & conducting Performance tests
- Evaluating performance data
- Carrying out Root cause analysis (as an add-on service based on client request)
- Providing Detailed metrics & Recommendations
Modus Operandi
- Evaluated & Identified the most suitable Open source Load testing Tool – OpenSTA for Phase I. (Loadrunner for Phase II, III)
- Identified critical Workflow
- Fixed tolerance limits for acceptability in terms of Failure like 4xx, 5xx errors that are common
- Execution of tests across various bandwidth, Virtual users
- Collected metrics and presented variety of statistics
- Confirmed the Server capability thru Intranet testing and internet testing
- Confirmed the portal capability based on Several VU load simulation
