<para>
Data will be transferred in chunks of this size, setting

increasing this value to 32768 if noticing otherwise
inexplicable slowdowns.

<term>
<parameter>memcache.hash_strategy</parameter>
<type>string</type>

<listitem>
<para>
Controls which strategy to use when mapping keys to servers. Set this value to
<literal>consistent</literal> to enable consistent hashing which allows servers
to be added or removed from the pool without causing keys to be remapped.
Setting this value to <literal>standard</literal> results in the old strategy
being used.
