It’s not highly visible, but we have a team within the Applications Technology Group that’s dedicated to optimizing the performance of the E-Business Suite.
This group covers it all: runtime performance analysis for the database, application and client tiers, as well as performance analysis of our own internal development environments. At any given time, they can be found analyzing JVM garbage collection parameters, JDBC connection pool logs, network roundtrips and latency, process address space allocations, and other related esoterica.
Interesting trivia: they maintain a comprehensive SQL repository with over 500,000 SQL statements used in a given E-Business Suite release, extracted directly from the source code, and the execution plans of these SQL statements based on volume-testing databases. E-Business Suite developers use this database to identify potential performance issues with their specific apps products.
Our performance team also works with selected vendors to create standardized (and independently audited) Applications Benchmarks. As of today, benchmarks are available for 11.5.9 and 11.5.10. Interesting reading.
Note: The graph shown above is for the Oracle e-Business Suite eBS Benchmark 11.5.10 using Oracle10g on HP ProLiant and Blade servers.
