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.
