I have been using DBMA to administer DBMail v2.2.10
On the home page of DBMA web interface, it displays only the top part of the
page.
I discovered the issue was due to a slow query in MySQL, after checking the
slow-query-log in MySQL.
The slow query is:
SELECT COUNT(*) FROM dbmail_messageblks;
Running this slow query took 138 seconds (2 min 18.09 sec)
SELECT COUNT(*) FROM dbmail_messageblks;
+----------+
| COUNT(*) |
+----------+
| 262788 |
+----------+
1 row in set (2 min 18.09 sec)
After optimizing the SQL, it took 0.27 seconds.
SELECT COUNT(*) FROM dbmail_messageblks use index(physmessage_id_index);
+----------+
| COUNT(*) |
+----------+
| 262796 |
+----------+
1 row in set (0.27 sec)
The diff below fix this performance issue for DBMA.cgi
6109c6109
< $dbh->prepare("SELECT COUNT(*) FROM $dbmail_messageblks_table
use index(physmessage_id_index)");
---
> $dbh->prepare("SELECT COUNT(*) FROM
> $dbmail_messageblks_table");
HTH other users of DBMA.
BTW, I posted this here because I can't find the forum/mailing list for DBMA.
And what's the best admin interface for DBMail?
