EJB perfomance regression: the enhanced pool seems to be less efficient than the simple pool
I observed a regression of the performance of the EJB in JOnAS 5.2.0-M2 compared to JOnAS 5.1.3.snapshot, with a web service implemented as a Stateless EJB (wsadd_ejb3). Using the enhanced pool instead of the simple pool for the EJB instances deteriorate the performance: 4850 calls per second instead of 6750 calls per second.
Use -Deasybeans.useSimplePool=true to work around this problem.
