System Requirements 
of Webserver Stress Tool

Test Client Details

Please find requirements for operating system, hardware, and network below.

Operating System

Webserver Stress Tool runs on all 32-bit versions of Windows (2003 R2 or later). Depending on your Windows version there are limitations in the number of users you can let run simultaneously. Please prefer older Windows versions for better performance, as outlined in the table below.
 

Hardware

Serious testing can be conducted with any better PC built in 2010 or later (at least a 1-2 GHz processor, 1 Gigabyte RAM, and a fast network connection). More CPU power and multithreading or multiprocessing will be helpful for high traffic scenarios (e.g. when several thousand users are simulated). Try to supply 1 GB of RAM, 2 GB should be enough even for high traffic scenarios. Webserver Stress Tool records the CPU load of the client machine during the test, so you can check after a test whether you need more processing power.

Network

For load tests the network connection between the test client and the server is critical. For the connection between the server and the test client you must provide the full total bandwidth that an equal number of real users would use when accessing your server!
