Stress and Volume Testing - Your Experiences?

Tarohann asks: "I work for a large software services company and I'm planning to write an article on Enterprise application Stress and Volume Testing (SVT) based on a couple of experiences I've had. For the most part I feel that most Enterprise SVT initiatives performed by companies at the enterprise level are flawed as they are done on ideal/non-production environments. I was wondering if anybody here has had any good/bad experiences or pointers (websites, books) I can refer to on this subject. Full credits will be given. Thanks, Slashdot!"
