Wouldn't that be impossible considering that New Posts may change several older posts under the Related Link Section?
New post shouldn't change the Related Link Section on older post - at least this is (in my opinion) the safer way. If the related links are just generated once when the post is created and stored in the database then the section won't change (and it's even faster). However, it depends on the plugin.
