I am having problem with my Moodle 1.9 on a Ubuntu server.
I get 100% CPU usage with 20 users, so I install PHP-APC with "apt-get install php-apc". I restart apache2 and I get this on phpinfo:
I don't configure nothing else, need I configure some parameters?
On the adminitsrator page on moodle, on Server -> Performance, need I to configure something on the "Cache Type"?
I will apreciate any help, I am trying to configure it lots of days and there is no solution yet.
Thanks for your help and best regards.
