Re: Speed up Java on i

Appserver4RPG is opensource, extendable, base layer of ArdGate (running in > 
100 installations in production, since about 10 years). It's multithreaded 
(using a threadpool), it has extended logging capabilities (log4j), wich 
could be used for profiling the application.
Running a single instance (one JVM), you could create your QR-Codes (or 
whatever you want) from multiple as400 jobs.
You could have multiple installs on the same box, running independable from 
each other (each of them using a JVM of its own).
You could run the java part of an installed instance on another box in your 
network (this could be as400, i5, system i, i or any other box with an 
installed JVM - linux, windows, aix...)
This would provide (nearly) unlimited scalability and could be implemented 
in less than 2 days.
