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