Why is the Laravel task scheduler heavy on CPU?

Question

Task Schedulers

Hello!
Commands are executed using the Laravel task scheduler (App\Console\Kernel.php).

protected function schedule(Schedule $schedule)
{
    $schedule->command('Cron --method=clear')->runInBackground()->everyMinute(); 
    $schedule->command('Cron --method=getData')->runInBackground()->everyMinute(); 
    ...
}

The commands themselves are located in App\Console\Commands and run controller methods.
The problem is that when you run commands, the processor (4 cores * 3600 MHz) is heavily loaded up to 100% and the site stops working.
Please tell me how can I solve the problem?

Answer 1

1. Laravel does not have any special scheduler, cron is used.
2. Every minute you run unknown doing tasks. Maybe you're counting a trillion digits of pi there.
3. There are no seers and soothsayers here.
PS Commands that launch controller methods are terrible.

Answer 2

See how hard this task is in itself without cron and what it does. Maybe there is some kind of resource lock, database, etc.
In itself, raising php, parsing and executing a script is a rather resource-intensive thing. If this needs to be done every minute, it might be worth writing a sleep daemon.
