How to enable alternate php cache?

[jasondhsd]

Hi I've been working with my host provider to solve my site's slow loading and they recommended to switch to fast cgi and apc cache. I've read that I'm suppose to go under global configuration > system and change the cache handler from File to Alternative php cache. But I only have File under drop down. How do I get joomla to utilize APC cache? Thanks. Running joomla 2.5.8

In order to utilise APC you will need to make sure that php-pecl-apc module is installed.

In redhat/centos/fedore simply type "yum install php-pecl-apc.x86_64" (assuming that you are running 64bit OS) and restart apache.

It looks like it is not installed yet. You can check it in the administration part with going to Site -> System information -> PHP Information. If you don't see APC there it is not installed.

In some cases you have to add it to your website php settings. Mostly you find them in the directory:
[yourdomain]/etc/php5. Look for a file called php.ini.
In this file you can add the following lines at the bottom:

Code: Select all

[APC]
extension=apc.so

Also keep in mind that you probably have to tune APC. You have to do that too in this file. Most important is the file apc.shm_size (amount of memory for APC).

Afterwards you can choose it in the Joomla Cache like you already tried. A warning: Don't change Session Handler there, keep it like it is. Otherwise it will destroy your site.

I can confirm that it makes your site much faster. Only when you change something, don't forget to clear the cache, otherwise you don't see the changes.

Ask your provider to help with installing it.

Good luck
