If you set the slow query log time to 0 then there are various tools
that will analyze your queries for you eg http://www.maatkit.org/doc/mk-query-digest.html
or http://www.mysqlperformanceblog.com/2006/09/06/slow-query-log-analyzes-tools/
(this will obviously dump a lot of data to your slow query log so you
don't want this running 24/7)
