That driver is for all the remotely modern HP cards. I think the one with performance problems was the builtin one they user to have (SmartArray 5i). AFAIK, the new builtins (6i) are a lot better. And the high-end add-on cards I've never had any performance problems with - linux and windows both. //Magnus ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
