Say Hi module (web/modules/custom/say_hi) provides 3 different forms to compare the different behavior of the form depending on the approach taken to process the request:

• /hi: Traditional approach, performing all the tasks in the main thread.
• /hi-batch: Batch API approach. Using a batch to maintain resources under control
• /hi-queue: Queue API approach. Using a secondary queue to perform the tasks during cron run

To add new users to see the difference between the different forms, new users can be added using drush genu 1000 to add new 1000 users.

To process the queue you can use the queue worker, triggering it via drush cron or run the queue specific drush command drush queue:run say_hi_greetings
