I changed it from single requests to a server solutions with a dataq. The
dataq will be created only once a job.
This gave me a positive result, but still too less.

I've a very special case of a customer.
Case: Printing a QR Code with the Swiss flag in the middle.
Printerfiles are not able to do that, QR-Codes yes, but not with an
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.
