Database timeout accessing wp_gallery_slides

Hi,
I have timeout issues trying to access the slides in a gallery.

I have installed a query monitor and I have discovered that in a gallery with 22 slides are made 1110 queries to the database!!!

This is the query that generate most of the issues:

SHOW COLUMNS
FROM wp_gallery_slides

and it is made 434 times.

It is necesary this query to be made so many times?

Thanks in advance.
