This roughly corresponds to a set of queries that happens for a large number of posts.

I think what's happening here has to do with the way that bbPress has a single "forum parent" for all BP-group-linked forums, so that changing one item can trigger recounts for many other unrelated ones. See #4761.

I'll examine this in more detail in the upcoming days.
