[sorry, hit send too early] This is a topic that could take pages of explanation: http://www.oreilly.com/catalog/hpmysql/ Are you running only on mysql on the box? That's a big issue. If so start with my-huge.cnf and tweak based on your usage patterns and the mysql manual. At a start, give mysqld a lot of memory. http://dev.mysql.com/doc/mysql/en/Server_system_variables.html Next, look at your queries using explain statements. You'll want to write your queries/add indices/create summary tables until you get the explains looking good. This too is a complex area. The mysql manual has a lot of info to start with: http://dev.mysql.com/doc/mysql/en/EXPLAIN.html Nothing will be fast until you utilize the cpu. We've found mysql runs very well on the G5. Our G5 XServe is about 2-4X faster than a DP 1.42 G4 Tower, depending on query. Some of that is the chip, some the bus, some the extra memory the G5 can take. It is of course specific to our queries and setup. --Ware -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
