There’s not a lot of single-core x86 computers left.

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.

If there’s only one job running, it can only run on one core.

Because this is recommended on: https://www.dragonflybsd.org/docs/newhandbook/Upgrading/

Or is a simple “make” sufficient to use all cores?
