Challenges

Featured work things we've made.​

  • Complicated application flow, with complex data inputs
  • High data dependencies between the three applications
  • Several scripting challenges due to the application’s security requirements
  • Test data volume, requiring a lot of dummy data to simulate the correct DB load (16 million+ active customers across India)

Solution

Solutions

  • Developed over 60 web-based and mobile API scripts using a mix of Fiddler, LoadRunner, and JMeter
  • Executed 150+ performance tests over a span of 8 months
  • Real-time monitoring and issue reporting using NewRelic APM
  • Supported DBA in analyzing Oracle AWR reports to highlight problematic queries
  • Worked in shifts over 24 hours to support on-time product delivery

Value Delivered

Value Delivered

  • Exhaustive testing revealed numerous issues in the server configuration, particularly around how the server manages concurrent connections. This was done by analyzing application thread dumps and OS logs.
  • Testing also uncovered that many plug-and-play modules on the application were not capable of handling high concurrency, forcing developers to create custom modules that helped the client achieve their concurrency goals.
  • AWR analysis uncovered more than 20 long-running and frequent queries, and optimizing those reduced DB server utilization by more than 20%.
  • The application was creating database connections at a ratio of 1:8 for every web request, which was deemed unacceptable. This issue was highlighted using real-time NewRelic monitoring over several tests.
