One good recommendation was from Joram in another post where he gave the usage of a Java ThreadPool executor with each thread starting Thu, 26 Sep 2013 09:37:02 GMT https://connect.hyland.com/t5/alfresco-archive/scalability-of-the-activiti-engine-in-an-enterprise-environment/m-p/152412#M107063 ambharath 2013-09-26T09:37:02Z Re: Scalability of the Activiti Engine in an Enterprise environment https://connect.hyland.com/t5/alfresco-archive/scalability-of-the-activiti-engine-in-an-enterprise-environment/m-p/152413#M107064 <HTML><HEAD></HEAD><BODY><SPAN>1) Don't think there is another approach, other than having a process with a service-task in it (with async=true) that starts any number of instances, using the EngineServices.
