    Default No. of copies for all transformations


    Is it a good idea to change the no. of copies>1 on all the transformations(approx 60)?
    All transformations are truncate and insert.
    Our server has 8 processors.

    Please let me know if it as an option so that the transformations can use all the processors and run faster than normal.
    Let me know if I am missing something here.

    I've done some performance testing on this topic and I believe that pdi already handles the thread management across the processors well so it doesn't make sense to try to tune it yourself.
