It’s a (very) simple but useful stress-testing tool: you create simple Worker classes in Java and the tool runs many of them simultaneously, displaying a summary of their status in a GUI window.
Being able to quickly create a stress-test cycle for your software (HTTP server, database, numeric, RMI, whatever) is very useful, and running a few instances overnight on several hosts can generate lots of load on your system.
The colored status windows give a useful overview of what’s going on, telling you when you find a way to bring your system on its knees. Assuming you want it to break in the lab, not in the user’s hands…
Many thanks to Thomas Rimmele of swissinfo, with whom we designed the current version of this simple tool.
Feedback is welcome, of course!
