'stress' is a tool to impose certain types of stress, including CPU load, I/O subsystem load, RAM load, and HDD load, on a system. Since benchmarks do not always answer some the questions that a systems programmer or sysadmin needs answered it can be useful to be able to put the system under a specified amount of load and then take a look at how a given subsystem or application program is behaving.
