We are building a data provisining system and consider using JBPM with JPDL. But we have encountered serious performance problems. I wonder if it is because of configuration of JBPM or it is just so slow. We have dsingned a simple workflow (linear, just passing few pices of data) with 12 nodes, deployed it into a database and in a loop we have loaded and run the process 100 times. When the definition was without subprocesses it took 7 sec. when we partitioned it into 3 subprocesses (and this is quite important feature for our project) it took 47 sec! For comaprision whan we used the classes from the user guide's chapter on graph oriented programming, running 1 milion processes took 8 sec.
