Stress Utility

URL : http://weather.ou.edu/~apw/projects/stress/ Summary : A tool to put given subsystems under a specified load Description : stress is not a benchmark, but is rather a tool designed to put given subsytems under a specified load. Instances in which this is useful include those in which a system administrator wishes to perform tuning activities, a kernel or libc programmer wishes to evaluate denial of service possibilities, etc.
