FWIW, I've experimented heavily with FS options, and found out that dir_index on ext3 doesn't help at all, it actually harms performance. 'noatime' and 'nodiratime' options do help a little. Also, 14000 subdirectories is not something that will cause 15 seconds delay - those 14000 subdirectories will always live in OS dentry cache anyway. -- Alexey Polyakov -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
