+ By default, <productname>PostgreSQL</> is configured to run on minimal
+ hardware. This allows it to start up with almost any hardware
+ configuration. However, the default configuration is not designed for
+ optimum performance. To achieve optimum performance, several server
+ variables must be adjusted, the two most common being
+ <varname>shared_buffers</varname> and <varname> sort_mem</varname>
+ mentioned in <xref linkend="runtime-config-resource-memory">. Other
+ paramters in <xref linkend="runtime-config-resource"> also affect
+ performance.
