    Extrapolation of data from a testing environment

    Extrapolation of data from a testing environment to a production environment.

    I have done a performance test in a testing environment, but this environment is different from the production environment HARDWARE wise; therefore I need to do an extrapolation of data, so if in the testing environment, the response time or the percentage of CPU used or any other variable had a particular value, then I can estimate these values in the production environment by doing an extrapolation process.
    Can anybody help me with this issue?
    Thanks

    That being said, it can be done. The amount of math involved means anyone without a mathematics degree is going to struggle, but it can be done. Advanced knowledge of statistics is required. Our capacity guys use

    You can look at some predictive models. However, any model needs to be calibrated in order to be accurate. Look for Open Network Queuing models and such. There are a lot of free tool, but these mostly used for academic purposes. Also, commercial tools are available.
