Sendmail not pumping efficiently??

your_shadow03 · 02-24-2009, 10:03 PM

I have setup a sendmail server and Client on the same RHEL Machine which should pump the mail at a certain speed from server to the Client. The RHEL MAchine is running on blade server.

Code:

cat /proc/cpuinfo | grep "processor" | wc -l
6

RAM = 16 GB

I tested the application in a simple RHEL MAchine (not on blades) and it was pumping mails at the rate of 100 mails on 4 sec.But the Systen which is on Blade ) is pumping very slowly at the rate of 100 mails per 1 min(:|}.
Can anyone help me with any settings to fix this.

[root@basic ~]# ps -auxf | grep -i sendmail

What I can see everything fine but what could be possible reason of it behaving so ??

Hi,

take a look at the queue specific parameters on sendmail.mc.

The most limiting factor from my experience is disk IO. Take a look at the systems IO behavior when delivering mail using iostat or sar.
