The test are all self made ;-)
I use it to have a simple benchmark to evaluate the different HW plattforms, cluster, JVM and JBoss versions perform.
I use a simple (configurable) mulltithread JavaApp and a simple SLSB to check RMI
and a simple servlet with JMeter for HTTP.
For our application we have (still in progress) a test suite to check the performance accross the different application version.
