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.

When there are thousands of links to be listed, it is better to split the map. Otherwise, hreflang is a good choice.
xmlsitemap module generates wrong links for languages
I don't fully understand why someone would need multiple sitemaps for different languages, but you certainly know better. Good luck!
xmlsitemap module generates wrong links for languages
Easy xml sitemap doesnt seem to offer multiple sitemaps for different languages, otherwise it seems a good solution for a single sitemap but then it doesnt make sense to exclude languages at all...
