laravel - Periodic spikes in CPU usage, possibly queue related? -


i added beanstalk queue application (running through supervisor).

i noticed cpu usage periodically spiking:

as far know, there's nothing in queue. i've restarted beanstalkd multiple times. noticed when stop supervisor processes, cpu usage goes zero.

is normal behavior queues though there's nothing in queue? there way make spikes less severe?

and if helps, here's supervisor worker configuration:

[program:laravel-worker] process_name=%(program_name)s_%(process_num)02d command=php /var/www/laravel/artisan queue:work beanstalkd --sleep=3 --tries=3 --daemon autostart=true autorestart=true numprocs=8 redirect_stderr=true

thanks.

the short answer takes effort load relevant php files, , check queue new items, regardless of work in queue, done.

enabling opcache used command-line scripts, faster versions of php, v7, help, longer sleeps between runs pause if there no jobs in queue.
