Requirements for the Web Capacity Analysis Tool

The Web Capacity Analysis tool must have the following features:

It must be easy to run and automate.
It must display hardware and software configurations along with results, whenever possible to provide a comprehensive summary.
It must produces one comprehensive rating number if possible.
It must include at least one simple test that covers all functionality and runs in less than one hour.
It must cover all possible functionality, including basic file transfer, Common Gateway Interface (CGI), Internet Server API (ISAPI), and Secure Sockets Layer (SSL) / Private Communications Technology (PCT) protocols. It should be easily extendible.
The server tested must be an uncontrolled entity ("black box.")
The tool must run multithreaded clients in a single client process. Using threads instead of multiple processes makes client bottlenecks less likely and increases the load on the servers.
