FYI, Paul... here is an example slow query that we see in the logs:

# Query_time: 7  Lock_time: 0  Rows_sent: 1  Rows_examined: 26769
SELECT t.forumid, t.threadid, t.title, t.replycount, t.lastposter, t.lastpost
FROM thread AS t
LEFT JOIN deletionlog AS deletionlog ON(deletionlog.primaryid = t.threadid AND type = 'thread')
WHERE forumid = 30 AND lastpost > 1021388850 AND visible = 1 AND open <> 10
AND deletionlog.primaryid IS NULL
ORDER BY lastpost 
LIMIT 1;
