Did you know that with the
free SOAPbox tool and with Vordel's
XML Gateway you get a command-line tool which will send traffic to a Web Service and simulate load? Check it out yourself. The tool is called "SR" (Service Request)). With its parameter options it allows you to perform a load test, to send an attachment, and to perform SSL. After it runs its test, it presents you with statistics about the response times from the Web Service. It's a good part of any SOA or Cloud API practitioner's tool-belt.
