Hi Colin, Thanks for the hint. No, i started 5 jvm jobs. Here it's a dev box, only 1 core.

I would suggest using parallel streaming. Its pretty easy to do in java and allows you to make use of all cores. https://www.geeksforgeeks.org/what-is-java-parallel-streams/ Ive never done this on ibmi but it works well on windows, so not sure what it would do to your overall system performance if you have other things running on the box...
