Hi Lambertus,

Use --max-jobs.

To summarise:

If --max-jobs is not specified, you get 1 thread no matter how many
cores you have.

If --max-jobs is specified, you get as many threads as you have cores.

If --max-jobs=N is specified, you get N threads.

The help blurb says this in another way.

Cheers,

Mark
