 ## Background & Purpose
 WooCommerce even with CRUD classes in core, still uses a custom post type for orders. By moving orders to use a custom table in the site database, will improve store orders performance.
 
+### Here's how
+
+WooCommerce saves more than 40 custom fields per order— including those from plugins— inside the wp_postmeta table. If your store gets ~40 per day, that's 1600 rows (40 * 40) added to the postmeta table in a day. 
+
+In one month that number can be 48,000 new rows (1600 * 30) added to your postmeta table. The more rows in a table the longer it will take for a query to execute. WooCommerce Order Tables creates a new table for WooCommerce orders which would cut that number tremendously by making each custom field into a column so that 1 order = 1 row.
