The major problem with both patches is that they use `COUNT` and `JOIN` and 
`GROUP BY`. This does not scale well for such big tables. What we do now is to 
store the number of sitelinks per item in a "wb-sitelinks" page property (in 
the page_props table). `pp_sortkey` is a numeric field that can be accessed 
then, and possibly ordered (need to check this). This should already be 
deployed, as far as I know.

So whoever wants to pick this up, please pick one of the existing patches, 
reopen it and change the SQL query to query pp_sortkey in page_props instead.
