    Hi,

    as far as i know this setting (if activated) should increase the performance of ur workflow. The task (which sould be performed) will be splited i think.



    Possibly it has something to do with (mulitcore) but i am not 100% sure.

    hi

    in my experience, if you only have 2 core processors, it doesn't really help. but I don't know yet how it performs on let say quad-core.
    nevertheless, you should have high amount of RAM, 4 gigs will help, I you do a large data analysis.

    I have quad core and 16GB, and I never use it. Doesn't seem to make much difference.

    Hi there,

    it only makes a difference if there is something which can be performed in parallel. For example, if you have two (independent) subprocesses which would have to be performed sequentially otherwise. In such cases, RapidMiner tries to perform those subprocesses in parallel which should - if you have at least two cores and both subprocesses need about the same runtime - decrease the total runtime about the half.

    Cheers,
    Ingo
