I'm using Laravel queue system for the first time and I have some questions about the architecture :

The queue listener runs as a daemon , what's the benefits of this approach against a frequent cron job ?

As a test , I created a Queue::push which logs some string with Log::info and saw that 3-5 logs are added per second. What should I do to run parallel queues? Another approach is to do more on each Queue::push ( for example a loop for multiple logs in this example ) the problem of this approach is that it can't be used in some cases (for example when a user sings up and a confirmation email is sent to him). What should be done in these situations?
