Processing multiple yii2-queue jobs at once

I have a sync job that takes 30-60 seconds each job. We have yii2-queue working, but have found that running 1 job at a time doesn’t work out very well.

The docs for running multiple workers is very systemctl specific:

Just so I’m clear, if I want multiple workers working my job queue, I just need to launch multiple instances of queue/listen?

For example, if I want 5 workers, then I should start 5 of these:

$ yii queue-sync/listen

Is there anything I’m missing?
