+     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.
