Hi,

I'm wondering why my dbmail (2.2.13) installation is performing so slow on imap 
search and sort operations. We're using a 64 Gb/SAS MySQL server dedicated to 
dbmail as storage (around 300 Gb in use) and serveral 4 Gb machines for the 
dbmail-imap processes.

I did try a session by telneting to port 143 and than the following happens:

.. LOGIN "username" "password"

Dbmail responsed immediatly with it's OK. Then:

.. SELECT "INBOX"

And again it tells within an eyeblink that there are 1039 messages in the 
INBOX. Then:

.. SEARCH ALL UNDELETED

This response takes 56.3 seconds (!) for those 1039 messages. And a

.. SORT (DATE) US-ASCII ALL UNDELETED

took 38.6 seconds.

In this time there seems to be no query running on the MySQL server (or it must 
run for a very short time so my 1 second updates with mysqladmin doesn't seem 
to catch it).

Anyone an idea how to improve the performance?

Regards,
Erwin
