I am sort of confused. If you ask them to improve performance do they just ignore you? I know with the current project I am on, we have a very specific cpu and memory usage requirement. This specific requirement is silly in what the customer demanded, but it is a requirement and it is our job to make it happen. There is no option to ignore it. Don't give your developers an option. Set specific goals based on your target environment. The product is not ready to ship until it meets those goals. At the same time you have to be reasonable. Your goals must be based on what the applications are actually doing. If they are very graphics heavy, you may need faster hardware than if its just a standard office style app. Giving them slower hardware will never make impossible things possible.
