It's been falling back to PRIMARY instead, which is really very inefficient for a profile that hasn't posted in a few months. Even though forcing the index will cause a filesort, it's usually going to be better. Even for large profiles it seems much faster than the badly-indexed query. --- diff --git a/classes/Profile.php b/classes/Profile.php index 5de35c191a..54f557ea7c 100644 --- a/classes/Profile.php +++ b/classes/Profile.php @@ -225,31 +225,62 @@ class Profile extends Memcached_DataObject { $notice = new Notice(); - $notice->profile_id = $this->id; + // Temporary hack until notice_profile_id_idx is updated + // to (profile_id, id) instead of (profile_id, created, id). + // It's been falling back to PRIMARY instead, which is really + // very inefficient for a profile that hasn't posted in a few + // months.
