To clarify: 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. Core dates: Box: IBM i9, single core, 32 MB mem, V7R4 Java: JVM Java 8SE 32 bits Code-Pics: 500 jpg / 90 sec. on IBM i vs. external webservice = 500 jpg / 35 sec.

In the past, I've found pure Java to be faster than trying to invoke from RPG. What OS version? What Java version? 32/64 bit? Have you tried to determine where the time is being spent?
