URL Stress is a powerful, robust, free client java application that adds load to a specific URL. It simulates parallel user connections by spawning threads and pinging the server repetitively. You can monitor failures and response rates to determine load capacity. For best performance, install and execute URL Stress on multiple computers simultaneously.
* As is Software - no warranty of any kind is expressed or implied. URL Stress does not include spy-ware, trickler, or advertisement features.
