sysutils/stress 1.0.4p2 OpenBSD

stress is a tool which imposes a configurable amount of CPU, memory, I/O, or disk stress on a POSIX-compliant operating system. It is written in highly-portable ANSI C, and uses the GNU Autotools to compile on a great number of UNIX-like operating systems. stress is not a benchmark. It is a tool used by system administrators to evaluate how well their systems will scale, by kernel programmers to evaluate perceived performance characteristics, and by systems programmers to expose the classes of bugs which only or more frequently manifest themselves when the system is under heavy load.
