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'

NAME
exiqsumm - Summarising the queue SYNOPSIS
exiqsumm [-a] [-c] DESCRIPTION
The exiqsumm utility is a Perl script which reads the output of exim -bp and produces a summary of the messages on the queue. Thus, you use it by running a command such as exim -bp | exiqsumm The output consists of one line for each domain that has messages waiting for it, as in the following example: 3 2322 74m 66m msn.com.example This lists the number of messages for the domain, their total volume, and the length of time that the oldest and the newest messages have been waiting. By default the output is sorted on the domain name, but exiqsumm has the options -a and -c, which cause the output to be sorted by oldest message and by count of messages, respectively. The output of exim -bp contains the original addresses in the message, so this also applies to the output from exiqsumm. No domains from addresses generated by aliasing or forwarding are included (unless the "one_time" option of the redirect router has been used to convert them into 'top level' addresses). BUGS
This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches would be greatly appreciated. SEE ALSO
