 756                 Using a shared memory system such as Turck MMCache or Memcached will speed
 757                 up MediaWiki significantly. Memcached is the best solution but needs to be
 758                 installed. Specify the server addresses and ports in a comma-separted list. Only
 759                 use Turck shared memory if the wiki will be running on a single Apache server.
