I have a Joomla site causing very high (php) load on the server. I have already ran the MySQL slow log feature and it doesn't appear to be MySQL.
What are some ways to analyze a Joomla site to determine what causes the high php load?
Example of highest processes for the day:
testing1 testing1.com 27.32 0.53 0.3 Top Process %CPU 179 /usr/bin/php /home/testing1/public_html/index.php Top Process %CPU 138 /usr/bin/php /home/testing1/public_html/index.php Top Process %CPU 137 /usr/bin/php /home/testing1/public_html/index.php
Using latest 1.5 Joomla on a CentOS server running Apache/MySQL. I have full/root access to this server, so whatever tools are needed I can install.
I know the general idea is that a number of 3rd-party components are probably causing this, but how can I determine which ones (without removing/disabling them)?
