Hardware requirements for high density robots
:   For a high density robot, where multiple robots execute jobs concurrently on the same Windows Server machine, you must multiply the minimum and recommended hardware requirements by the number of runtimes.
:   For example, with three users concurrently executing jobs, the minimum requirements are:

    * 6 cores of Intel 1.8GHz 64-bit (6 cores of 1.8GHz 64-bit per runtime)
    * 12 GB of RAM (4 cores per runtime)
