A simple and easy method of load testing a REST service using The Grinder open source load testing tool is as follows:
The following script gives an example of this method in the case of REST PUT request using a JSON request message. (XML request message would be similar).
Script
Output

- use the appropriate REST method on the HttpRequest object:
