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.
