Every click in Moodle is very slow, avarage 5-6 sec page loading. Examinated the configurations, and i saw that when i click in Moodle, the php-cgi.exe process use one core and load up to 100%. after 4-5 sec, it fall down, adn Moodle page load well, but slow. I set up fast CGI on IIS, enable opcache, but still slow. Any idea? What is the possibility problem?
