Running a PHP server, in production, without a cache seems now quite unrealistic. You may now choose between APC, eAccelerator and XCache, all available in remi (or remi-test) repository, if you use PHP 5.3 or 5.4.

Of course, only one can be installed.

Installation, for Fedora, or Enterprise Linux with PHP 5.3

yum --enablerepo=remi install php-xcache

Installation, for Enterprise Linux with PHP 5.4

yum --enablerepo=remi,remi-test install php-xcache

You can also install the xcache-admin which provides the administration panel, with apache configuration.
