Novell RBPM Best Engine Settings

Ok so I've been trying some of the settings for the workflow engine and found that these seem to work the best for us:

What I have however found is with about 5000 workflow requests the system does seem to choke a bit. I would recommend giving some good spec server to the server where you are going to run the workflow engine and assign another server as the 'front-end' server. This way the user experience should not be affected.
