Agreed. Text added to install docs: <para> 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 <![%standalone-include[the documentation]]> <![%standalone-ignore[<xref linkend="runtime-config-resource-memory">]]>. Other parameters in <![%standalone-include[the documentation]]> <![%standalone-ignore[<xref linkend="runtime-config-resource">]]> also affect performance. </para> -- Bruce Momjian | http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
