I've a very special case of a customer.

Case: Printing a QR Code with the Swiss flag in the middle. (Direction!)

Printerfiles are not able to do that, QR-Codes yes, but not with an embedded

So I've wrote a small ZXING Java program and a colleague a DataQ server
program to prevent multiple starts of the JVM.

But it's still too slow! For 1000 QR Codes needs my i9 3 Min and the
customer talks about 2 Million documents with a QR-Code.

How can I achieve much more speed to run the java prog?

This customer wants a full IBM i solution.

Who can give me a good advice.

Thanks and take care.
