I have an periodic performance issue on a self hosted wordpress site on IIS. Seems like every exactly 10 secods, something clogs the CPU up to 100%. enter image description here
I can clearly see it's something from the site itself rather than the environment because the processes that cause it are the php-cgi.exe processes.
How can I debug the issue and find out what is being called? And from there ofcourse find the addon ? Is there somewhere when i can find a list of scheduled tasks that i could see (maybe find all tasks that are schedueled for every 10 seconds)?
