Hi, I'm performing evaluation for the workflow products and the point is the performance. I've downloaded and installed 4.0.0. Then i modified EndProcessInstanceTest so the process from process.jpdl.xml will execute about 10.000 times. Also logging was disabled by changing logging.properties. Actually the process is simple : it has only start/end states, but i takes 33 secs(!!!!!) to execute 10.000 iterations of this: for (int i = 0; i < ITERATION_NUMBER; i++) { Execution execution = executionService.startProcessInstanceByKey("NoOperation"); if (!execution.isEnded()) { fail(); } } Am i misunderstanding something ? Our case when request comes in and is processed by appropriate workflow. Should i start new process for that every time reques is coming or using the only one process instance (if possible) to achieve better performance?
