Background jobs improve performance by offloading time-consuming tasks like sending emails. This snippet uses ActiveJob with Sidekiq to send a welcome email asynchronously. The SendWelcomeEmailJob finds the user and triggers the mailer, while the UsersController queues the job when a new user signs up. This prevents slow request times and ensures a smooth user experience. One challenge is setting up Sidekiq with Redis, but once configured, it enhances app efficiency.
