Ok, that is working. But it becomes very slow after a few iterations and the memory is also getting full up to a certain level (Depending on the settings of them VM). Furthermore is the CPU not very busy all the time. So my question is, can I tweak the performance a little bit? In addition Taverna does not clean up the derby database in the background although the workflow is complete. In my case the size is now about 40gb. I can delete it by hand all the time but that can't be the intention. Also throws taverna OutOfMemory errors after a restart --> ERROR 2010-11-04 14:06:05,939 (net.sf.taverna.t2.workbench.ui.impl.Workbench:117) - Uncaught exception in Thread[Deleting old workflow runs,2,main] java.lang.OutOfMemoryError: Java heap space Cheers, Andreas ------------------------------------------------------------------------------ The Next 800 Companies to Lead America's Growth: New Video Whitepaper David G.
