Comment(by ptahdunbar):

 The primary bottleneck is on the menus page loading all the objects (post,
 pages, media, cats, tags, etc.) from the db and looping through them which
 is super memory intensive.

 I discussed this with ryan and he came up with the idea to limit them by
 15 (excluding pages, so that all pages are retrieved). Links aren't a
 bottleneck (yet) as it's new to WordPress so they also won't be limited.
 And I'll make sure categories aren't limited too.

 FYI: There will be a filter to remove that limit for the other objects.
