 788                 up MediaWiki significantly. Memcached is the best solution but needs to be

 790                 use Turck shared memory if the wiki will be running on a single Apache server.

 901                 <p>If you need to share one database between multiple wikis, or
 902                 MediaWiki and another web application, you may choose to
 903                 add a prefix to all the table names to avoid conflicts.</p>
 904
 905                 <p>Avoid exotic characters; something like <tt>mw_</tt> is good.</p>

 914                 You will only need this if the database and/or user account

 916                 Do <em>not</em> type in your machine's root password! MySQL
 917                 has its own "root" user with a separate password. (It might
 918                 even be blank, depending on your configuration.)
