Disclaimer performance benchmarks are only a guide to relative performance, and to a certain extent limited. The only performance benchmark that will have full meaning for you, will be the one you run, on your new machine, using your applications and employing your work flow. Given this, while we believe that the information we will provide you will give a general guide to relative performance, and we will endeavor to make sure that it is as accurate as possible, we offer no implied or actual guarantee that this is so. People who need mission critical data, should be doing performance testing in-house.
