You mean that jbpm console starts slow? It takes a time to deploy all beans, but after then it is quite fast. Start of JBoss application server is for me about 10-15 seconds and a have more beans(applications) in it, not only jbpm.
super slow.... 1 minute... lucky you... we've had apps on Weblogic that took 15 minutes to start up... In my local JBoss (1GB, 1.6 GHz single core laptop) it takes 15 seconds also... what are the specs of your machine? Maybe you can analyze debug logging to see where the delay is.
BTW, jBPM does not use jsp's, it uses facelets.
