OpenJ9 optimization pack

The OpenJ9 optimization pack enables the ability to optimize Java applications based on the Eclipse OpenJ9 VM, formerly known as IBM J9. Through this optimization pack, Akamas is able to tackle the problem of performance of JVM-based applications from both the point of view of cost savings and quality of service.

To achieve these goals the optimization pack provides parameters that focus on the following areas:

  • Garbage collection

  • Heap

  • JIT

Similarly, the bundled metrics provide visibility on the following aspects of tuned applications:

  • Heap and memory utilization

  • Garbage Collection

  • Execution threads

Component Types

The optimization pack supports the most used versions of JVM.
