   I installed super cache and it really makes my wp very fast. But can it cache the sql embeded internally ?

   for example:

   <?php
   $authorID = $wpdb->get_var("SELECT post_author FROM $wpdb->posts WHERE ID = '2'");
   ?>

   Will the result be cached?

   I am also very curious about the rule that super cache do a cache. Anyone give me some tips?

   Thanks very much!

   Sort of. It'll be cached because the output in the page will be cached, but you'll need an object cache to cache the actual result by using wp_cache_update() and wp_cache_get() ..

   But I searched "wp_cache_update" and get nothing in Google nor in your blog.

   So can you give me some further tips :)
