CTO of XDA Developers.

Linux systems are my specialty. As with any good system administrator, I dabble in networking, storage, virtualization, Android, and more.

LOPSA since 2008

I enjoy spending time with my family, social media, gaming and going backpacking. I have also blogged professionally for MakeUseOf, Lifehacker, and my own personal blog about system adminstration.

comment php5-fpm spike, wrong configuration?
It is really impossible to know without seeing the said scripts that are hitting PHP. Are you hitting CPU or memory limits? You said it is using 70-80%, what was it before? Is it slowness in PHP or in the network latency on the ajax scripts?

comment How to diagnose PHP server execution times to reduce them?
As others have stated, if you have eliminated the PHP processing time, then likely it is the setup time. Spawning the php process, reading the file, etc. Personally I like php-fpm running all the time, plus APC or Xcache for file caching. Try that setup and see how it impacts your PHP load times.
