Hi poddys,
Please take a look at the help page -> “Is my site using an opcode optimizer?” Generally this behavior happens when your site is using eaccelerator, or stacking extensions like ioncube + apc. Any extension which hampers P3’s ability to get an accurate backtrace or break’s php’s tick handler function will cause this behavior.

Thanks for the reply Kurt. We aren’t running any accelerators or caching on the site, so I don’t know why the plugin wasn’t working.
I did find mo-cache (http://wordpress.org/plugins/mo-cache/) which appears to have helped a lot with our performance issues, much of which seems to be caused by WYSIJA which takes forever looping through pomo amd mo when loading.
Will likely revisit P3 when I have evaluated the results from a couple of other server/site changes.

Aha, I read this (very informative)m post on your site Kurt http://kpayne.me/2013/12/24/write-your-own-code-profiler-in-php/ and we are using Zend Optimiser, which is probably what affected the results.
