German company Paessler is probably best known for PRTG, its tool that helps you monitor your computers and network. Until today, the company also used to sell a product called Web Stress Tool, which can simulate multi ple users from a single PC in order to help you discover how well your web site responds to heavy usage.
Now, though, the company has decided that it wants to focus its business efforts on PRTG, and has therefore made the web stress tool freeware. The product used to start "from $250", according to Paessler's web site, so this move to freeware represents a bargain for anyone who runs a web site and wants to check that it works efficiently.
The program is a 6 MB download from http://www.paessler.com/tools/webstress and is malware-free according to VirusTotal and Web of Trust. Simply install it on any Windows PC, set up the parameters for your desired test, and click the Start Test button. Just be careful not to have it simulate thousands of users if you don't think your site is up to the job, and be cautious about directing its potential power at anyone else's site too!
