I'm not sure if this is the right place to put this so let me know if i should be looking elsewhere. I have a 2008 r2 server running iis 7.5. It is setup as dual core with 8GB of ram as a VM. I set this server up a while ago and its been running fine up until now. When i setup the server i ran the microsoft web platform installer to setup wordpress and make this server a wordpress server for a user group on our network. They have recently made me aware that the site is taking a long time to load. The server isn't using that much ram but i have noticed that there is one instance of php-cgi.exe 32 using 50% of the cpu. Its not constant, I would say it stays at 50% for about 6-8 seconds then drops to low utilization for a few seconds then will go back to 50%.
I assume this is what the problem is but I don't know how to fix it. Can anyone help?
Thanks.
