After patch installation I can see a single query for all custom fields ( as opposed to a separate query for each custom field before the patch).
However ,I just want to point out ( though this is a different issue) that the fields are displayed quite messy and improperly , mostly in the front-end. This may have to do with me not knowing properly the management of custom fields...
