I'm running a custom benchmark which simulates an intensive database access to a J2EE aplication I've migrated from OpenEJB + Tomcat 5.0 to JBossAS 4.0.4: A single client, requesting 1, 10, 100, 1000 and 10000 ocurrences of the test case Multiple clients (1, 10 and 100 threads) requesting 1, 10 and 100 ocurrences of the test case The J2EE aplication uses the DAO pattern for persistence.
