stress Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies stress-1.0.5.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).


stress - tool to impose load on and stress test a computer system

What is stress?

stress is a tool that imposes a configurable amount of CPU, memory, I/O, or disk stress on a POSIX-compliant operating system and reports any errors it detects.

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.

stress needs your help. If you are a programmer and want to help a nice project, this is your opportunity.

The original stress went unmaintained; the source of the last version, 1.0.4, was imported from Debian. After, patches from Debian and other changes were applied to create the 1.0.5 release. The details of each release are registered in the ChangeLog file. Now, stress is maintained by volunteers under Resurrecting Open Source Projects.
