Hi Gary the Hello World sample is not a real application. It brings up the JVM for just a few statements and doesn't even use the optimization/caching provided for often requested functions. Try to run a real Java application. Of course it's more overhead compared to old cobol applications, but it might save a lot of development resources and in these days young people don't know about cobol. We run two Java applications on the z/OS one runs the whole day using JMS and JDBC and performance isn't that bad.
