Hi,
On AS/400, you have the option to optimize your Java application with the Create
Java Program command.
CRTJVAPGM creates a hidden service program, associated with your class file, that
improves performance. CRTJVAPGM also has an OPTIMIZE parameter that allows
you to select the level of optimization for your service program.
Note: It’s advised that you run the CRTJVAPGM command on all Java classes, JAR files,
and ZIP files you create.
Regards
