Describe your issue or idea
When I upgraded a site from Drupal 6 to Backdrop CMS, I noticed front-end pages getting sluggish, while the back end stayed quick and snappy. When removing the menu block, the front-end of my site was also quick and snappy.
After much further digging (thanks the devel query log!) I have tracked the problem down to the function menu_tree_check_access() which adds an additional 1141 database queries to my page.
It's true - my menu tree is quite large. I still think there's something we could do to speed this up. I don't see why these queries need to be run uniquely for every visitor on every page of my site - when the links are the same on every page.

Hi Francis. Yes, what config do you have in staging for it? You might have configs like: field.field.field_video_embed field.instance.node.page....
