Subject: [Dbmail] Very slow database


Hi all,

I have some issues with my database. Everytime there is some database
action it is extremely slow and the mysql server is putting lines in the
"slow" log file.

Here is some from the log file:

# Query_time: 56  Lock_time: 0  Rows_sent: 447  Rows_examined: 9444548
SELECT message_idnr,headername,headervalue FROM dbmail_headervalue v
JOIN dbmail_messages m ON v.physmessage_id=m.physmessage_id JOIN
dbmail_mailboxes b ON m.mailbox_idnr=b.mailbox_idnr JOIN
dbmail_headername n ON v.headername_id=n.id WHERE m.mailbox_idnr = 2700
AND message_idnr BETWEEN 15651805 AND 16208824 AND lower(headername)  IN
('date','to','cc','from','subject','x-priority','importance','priority','content-type');

# Time: 070220 10:10:13
# [EMAIL PROTECTED]: dbmail[dbmail] @  [10.0.0.10]
# Query_time: 55  Lock_time: 0  Rows_sent: 447  Rows_examined: 9444581
SELECT message_idnr,headername,headervalue FROM dbmail_headervalue v
JOIN dbmail_messages m ON v.physmessage_id=m.physmessage_id JOIN
dbmail_mailboxes b ON m.mailbox_idnr=b.mailbox_idnr JOIN
dbmail_headername n ON v.headername_id=n.id WHERE m.mailbox_idnr = 2700
AND message_idnr BETWEEN 15651805 AND 16208824 AND lower(headername)  IN
('date','to','cc','from','subject','x-priority','importance','priority','content-type');

# Time: 070220 10:16:00
# [EMAIL PROTECTED]: dbmail[dbmail] @  [10.0.0.10]
# Query_time: 55  Lock_time: 0  Rows_sent: 2825  Rows_examined: 9444701
SELECT message_idnr,headername,headervalue FROM dbmail_headervalue v
JOIN dbmail_messages m ON v.physmessage_id=m.physmessage_id JOIN
dbmail_mailboxes b ON m.mailbox_idnr=b.mailbox_idnr JOIN
dbmail_headername n ON v.headername_id=n.id WHERE m.mailbox_idnr = 2700
AND message_idnr BETWEEN 15651805 AND 16210400 AND lower(headername)  IN
('date','to','cc','from','subject','x-priority','importance','priority','content-type');

I am not sure if the "Rows_examined" section is ok. But allmost 9,5
million rows looks very mucht to me. When i take a look in the mailq I
found the following messages:

I hope someone have a clue.

Thx in advance.
