Stress testing is a form of testing that is used to determine the stability of a given system or entity. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results or the system crashes.
Stressapptest is a user-space test, primarily composed of threads doing memory copies and directIO disk read/write. It allocates a large block of memory (typically 85% of the total memory on the machine), and each thread will choose randomized blocks of memory to copy, or to write to disk. Typically there are two threads per processor, and two threads for each disk. Result checking is done as the test proceeds by CRCing the data as it is copied.
