Optimizing Cron Jobs and Scheduled Tasks for Real-Time Processing Without Overloading Processes

I am currently using Laravel 10 and PHP 8.3 on a CPanel hosting environment. I am facing issues related to optimizing cron jobs and scheduled tasks, particularly for real-time tasks that need immediate processing, such as generating sitemaps and handling live chat. These tasks sometimes cause an overload of processes when running simultaneously, and I need a way to optimize the system to run smoothly without affecting performance.

Issues: Overloading Processes: When cron jobs or scheduled tasks run frequently (e.g., every minute or second), the number of processes can exceed the hosting limit, which affects system performance.

Need Optimization for Real-Time Processing: Tasks like generating sitemaps or handling live chat messages need to be processed immediately, but running cron jobs on a schedule may not meet the low-latency requirement for these tasks.

System Information: Laravel Version: 10 PHP Version: 8.3 Operating System: CPanel Queue Driver: Redis Current Cron Job Setup: Running scheduled tasks using php artisan schedule:run

Use Case Scenarios: Generating Sitemap: Sitemap generation jobs require continuous processing without overloading the system. Handling Live Chat: Chat messages need to be processed immediately, but the system may struggle with too many simultaneous processes.

Request: Could you provide guidance on how to optimize cron jobs and scheduled tasks to prevent process overload and ensure real-time tasks (like sitemap generation and live chat handling) can be processed efficiently, even under hosting limitations?
