Comment (by boonebgorges):

 In [changeset:"34544"]:
 {{{
 #!CommitTicketReference repository="" revision="34544"
 Improve pagination internals in `WP_Comment_Query`.

 `WP_Comment_Query` will now report the total number of comments matching
 the
 query params (`comments_found`), as well as the total number of pages
 required
 to display these comments (`max_num_pages`). Because `SQL_CALC_FOUND_ROWS`
 queries can introduce a lot of overhead in some cases, we disable the
 feature
 by default. Pass `no_found_rows=false` to `WP_Comment_Query` to enable the
 count. (We use the negative parameter name 'no_found_rows' for parity with
 `WP_Query`.)

 Props wonderboymusic, boonebgorges.
 See #8071.
