I need to do performance testing on an .org. I have read the Salesforce documentation on the subject here: https://developer.salesforce.com/blogs/engineering/2013/09/performance-testing-force-com-application.html

The only tool specifically mentioned is Loadrunner, has anyone use this sucessfully for load testing? Specifically the community edition?

Has anyone used any other tool? If so what did you use? Essentially I can find very little detailed documentation on performance testing and am looking for more inforamiton and experiences.
