Optimizing exim performance

Hi,

Recently, I experienced that exim was slow in sending outgoing mail, it was spending a lot of time in the queue, resulting in customer complains.

I came across an article in the internet to optimize the performance of exim in the server. However, the location of the exim.conf is not in /etc/exim.conf in my server. It is /etc/exim4/update-exim4.conf.conf. I just want to confirm if this is the correct file to make the configuration changes to?

Also, one of the steps given to optimize the performance is to :

Quote:

Change how many queue runners that are spawned off. In /etc/init.d/exim change: QUEUE=5m. This ensures that a new queue runner was created every 5 minutes. How often a new queue runner needs to be configured on a server depends on its load.

However there is no /etc/init.d/exim in my server, only /etc/init.d/exim4. I assume this is the correct file to edit, however, I do not find the keyword "QUEUE" in it. How do I edit this file for this option? I only see this two variables that I think are somehow related:

Code:

QUEUERUNNER='combined'
QUEUEINTERVAL='30m'

exicyclog

EXICYCLOG(8)						      System Manager's Manual						      EXICYCLOG(8)

NAME

       exicyclog - Cycle exim's logfiles

SYNOPSIS

       eximcyclog

DESCRIPTION

       The  exicyclog script can be used to cycle (rotate) mainlog and rejectlog files.  This is not necessary if only syslog is being used.  Some
       operating systems have their own standard mechanisms for log cycling, and these can be used instead of exicyclog if preferred.

       Each time exicyclog is run the file names get 'shuffled down' by one.  If the main log file name is mainlog (the default) then when  exicy-
       clog is run mainlog becomes mainlog.01, the previous mainlog.01 becomes mainlog.02 and so on, up to a limit which is set in the script, and
       which defaults to 10.  Reject logs are handled similarly.

       If no mainlog file exists, the script does nothing.  Files that 'drop off' the end are deleted.	All files with numbers greater than 01 are
       compressed,  using a compression command which is configured by the COMPRESS_COMMAND setting in Local/Makefile.	It is usual to run "exicy-
       clog" daily from a root "crontab" entry of the form

	 1 0 * * * su exim -c /usr/exim/bin/exicyclog

       assuming you have used the name 'exim' for the Exim user.  You can run exicyclog as root if you wish, but there is no need.
