Native optimizations are a set of functions that make the IBM® Toolbox for Java™ classes work the way a user would expect them to work when running on IBM i. The optimizations affect operation of IBM Toolbox for Java only when running on the IBM i JVM.
The IBM Toolbox for Java optimizations when running on IBM i are:
No change to the Java application is needed to get the optimizations. IBM Toolbox for Java automatically enables the optimizations when appropriate.
In order to gain the performance improvements, you need to make sure to use the JAR file that includes IBM i native optimizations. For more information, see Note 1 in JAR files.
When you do not use the JAR file that includes IBM i native optimizations, IBM Toolbox for Java works as if it is running on a client.
