Yes. Take sort_mem for example: OLTP_SM 1024 OLTP_LM 2048 OLAP_SM 4096 OLAP_LM 16384 WWW_SM 512 WWW_LM 1024 Workstation 1024 The basic idea is: More RAM => more sort_mem More concurrent queries => less sort_mem Larger data sets => more sort_mem Lots of grouped aggregates => more sort_mem -- -Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
