Stress Test Tool

Does anybody knows a stress test tool that i can use to see if my application and database is configured to handle a certain number of concurrent users? Its hard to debug the system without a stress tool because we dont know were to optimize the system either in the application or the tamino db itself. Thank you.

hello jolly,

where the actual mass loader is concerned, it is not a tool that you want to (or can) use in parallel. but it is the tool of choice for inserting large amounts of data in a single, controlled transaction.
if you want to simulate concurrent users, i personally like multi threaded java programs, but i was told that perl had similar propertis with less overhead.
