Right... and perhaps try MySQL Enterprise Monitor. A trial is available from mysql.com. It may give you hints on your mysql.cnf.

That's a lot of data to return, make sure you factor in data load and transfer time. You may try breaking your query into smaller parts and recombining the results in a scripting language. If you are searching on a range (i.e. date range), break the range into smaller parts and run multiple queries. Divide and conquer, it will scale better.
