Just installed this plugin, and have got it up and running successfully. I don't really understand the summary results though (see below). Says that total query time was 0.07002 seconds, but num_query time was 7.021 seconds. What's the difference between those two numbers, and can the long num_queries results point to something in particular that's causing my WP site to be slow?
Total query time: 0.07002s for 147 queries.
Total num_query time: 7.021 for 148 num_queries.
» Different values in num_query and query? - please set the constant define('SAVEQUERIES', true);in your wp-config.php
