Because the pool of threads already limits the amount of instances that can be created the thread local pool doesn't need any multi-threading synchronizations. So the effective throughput is the highest possible. The strict max pool will make certain only a limited set of instances are created. Most call originate from a pool of threads (remoting pool, servlet thread pool), so using the thread local pool is best. However for example the old EJB timer service creates a new thread per callback, so then you would need to use the strict max pool. In this case the thread local pool should suffice. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/631240#631240] Start a new discussion in EJB3 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
