I have 20 to 60 queries per second and MySQL is using up 50% to 70% of 
CPU. What optimizations have you done that you could recommend?

I am just starting to read up on MySQL and looking into optimizations.

Our queries are primarily  against a single table using index 
access. We use mySQl primarily in conjunction with Postfix so the queries are just 
lookups of email addresses.
