title: 100% cpu load on nginx + php-fpm with prestashop 1.5.4
body: <p>I managed to set up my VPS (single core CPU Speed:2.40 GHz Cache Size:512.00 KiB, 1 gig ram) with the prestashop/ubuntu 12.10 guide on <a href="http://www.howtoforge.com/running-prestashop-1.5.x-on-nginx-lemp-on-debian-wheezy-ubuntu-12.10" rel="nofollow">HowtoForge</a>. Everything is working, except for the extremely high CPU load, when 1 user opens 1 page the CPU loads shoots to 100% and still takes ~2seconds to process, I'm thinking there is something wrong in the php code, but I don't know how i can find out what is using up so much resources. Via htop I can see its php-fpm: pool, but that's not really helping me find out what is wrong with the code.</p>
  
  <p>The php5-fpm log is showing me only this warning:</p>
  
  <pre><code>[12-Apr-2013 12:36:16] WARNING: [pool www] server reached pm.max_children setting (10), consider raising it
  [12-Apr-2013 12:41:49] WARNING: [pool www] server reached pm.max_children setting (10), consider raising it
  [12-Apr-2013 12:56:26] WARNING: [pool www] server reached pm.max_children setting (10), consider raising it

  [12-Apr-2013 12:59:39] WARNING: [pool www] server reached pm.max_children setting (10), consider raising it
  </code></pre>
  
  <p>But as I did a little bit of looking around 10 isn't an unusual low number for this setting.</p>
  
  <p>I'm wondering if anyone could help me on the way to find out what is causing this issue?</p>
