ok, now i see that i haven't searched enough through the forum )) There are more performance test reports as you mentioned, jbarrez. 1) http://www.jorambarrez.be/blog/2008/04/14/short-jbpm-performance-showdown/ 2) http://processdevelopments.blogspot.com/2008/04/awsome-jbpm-performance-n... 3) http://www.jboss.org/index.html?module=bb&op=viewtopic&t=133647 The performance numbers reported there are different : 1) 9ms 2) 2ms 3) 0.4ms Actually, the performance numbers from 2) look similar to what i got so far (~3ms). But i run my test on a laptop without any changes in hibernation configuration. So there is still a place for optimization - adding more executor threads and changing hibernation configuration.
