Performance issue from commented out cache code.

Replies: 0

It looks like in the latest release you have commented out cache code from here: https://plugins.trac.wordpress.org/changeset/2129932/wp-facebook-pixel/trunk/inc/NSAUtilities.php

//$cache = get_transient($post_type.'_meta_keys');
//if($cache) return $cache;

This is causing these expensive SQL queries to run all the time with a big performance hit.

Can you add the cache code back in?
