title: Huge CPU load - php-fpm + nginx
body: <p>I use php-fpm with STATIC pools and the problem is that 2-3 pools from 20 are used with 80-100% CPU. Other php pools stay unused.</p>
  
  <p>My question is: <strong>Why other 17 processes stay unused?</strong></p>
  
  <p>We used AWS instance c4.large.
  Our docker image use 1024 Units of CPU and  2560 MB ram. </p>
