I think the newbie/l33t geek appeal of being able to say something's compiled and works with -O6 is probably worth more in terms of marketing than it is interms of actual technical merrit. Those that need 10K lookups per second should be serializing data into a bdb file with a unique key and not using a relational database (or helping out with pgsql-replication). :~) -sc -- Sean Chittenden ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
