  1. make itself will run one make job at a time unless you tell it to run more. If there’s only one job running, it can only run on one core.

  2. The “j” option is necessary for building if:
    1) you have more than 1 core
    2) you want to use more than 1 core

    Like Justin said, if you omit it, it will use only one core no matter how many you have.
