Nginx php-fpm high cpu usage
- by Piotr Kaluza
I have a problem with a high traffic wordpress, super high CPU load under nginx php-fpm, I am caching with apc, and memcached, spent 2-3 days tweaking configs and looking for answers it seems to me that php-fpm takes up all the cpu available no matter how many max_children i set if i set 5 then the load is 20% each, if i set 20 then the load adds up till 90% i tried static and dynamic
server is 2x3.0Ghz 6GB Ram SSD in raid 10 on ubuntu 12.04 x64
utpime:
17:27:51 up 2:19, 1 user, load average: 29.79, 28.08, 26.29
what can be the issue?
