Performance hit using custom fields (media) even when not displaying them

[bjrn]

On a site I thought the new custom fields would be a great addition. For a certain category I set a number of custom fields, including a few of the media type. This resulted in a significant performance hit loading the category blog page of that category. What's more, I set all of the media fields to be shown on on Administration only (not the site). Even so it seems like Joomla goes through and checks the fields and the values set, the folders and files in those folders.

Is there any way to prevent Joomla from churning through these values, files and folders when they aren't supposed to be displayed anyway?


Here's an example from my slow log
