I know you're all sick of hearing from me, but I'm passing this along anyway. Looks like I need to go back down to 6.5.3 for some reason. The following query is at the very heart of the site and it takes upwards of 15-20 seconds to run now. It used to be instantaneous. explain SELECT mailid, mail_date, mail_is_followup, mail_from, mail_subject FROM mail_archive WHERE mail_list=35 AND mail_year=2000AND mail_month=1 ORDER BY mail_date DESC LIMIT 26 OFFSET0; NOTICE: QUERY PLAN: Sort (cost=138.41..138.41 rows=34 width=44) -> Index Scan using idx_mail_archive_list_yr_mo on tbl_mail_archive (cost=0.00..137.55 rows=34 width=44) EXPLAIN Tim -- Founder - PHPBuilder.com / Geocrawler.com Lead Developer - SourceForge VA Linux Systems 408-542-5723
