New forums topics block is below the fold
Talking with Khalid.
This query is on line:
271 $sql = db_rewrite_sql("SELECT n.nid, n.title, l.comment_count FROM {node} n INNER JOIN {node_comment_statistics} l ON n.nid = l.nid WHERE n .type = 'forum' AND n.status = 1 ORDER BY n.nid DESC");
of the forum module. It is the new forum topics block that is loaded on every authenticated page. Unfortunately, it's frequently below the fold so it often unused for authenticated users. Perhaps simply disabling this block and making it able to be enabled would help.

This block was removed today
This block was removed today. We are waiting for results of the next MySQL slow query log to see if there has been a cumulative improvement. Initial observations were that it wasn't making much difference.
Cheers,
