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
