A J2EE benchmark from Sun for measuring the performance of EJB containers. It is designed to measure internal functions such as memory management, connection pooling and caching, rather than the graphical interface or database I/O. The ECperf workload focuses on manufacturing, supply chain management and order/inventory processing. Results are measured in Benchmark Business Operations Per Minute (BBops/min), which is the combination of the total number of customer transactions and manufacturing workorders processed in one minute. See J2EE.
