Re: Speed up Java on i

So I've wrote a small ZXING Java program and a colleague a DataQ server

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?
I would suggest making the java code a server function that runs all the time waiting for requests to generate the QR code. That way the java startup penalty isn't incurred every time it's invoked.

For a single function server like that, I would suggest using a data queue to listen for requests and a thread pool to manage the work load.
