I have a mailing list server where an application sends mails to list members using /usr/sbin/sendmail ( on commandline)
When the mailing is going on I find that /usr/sbin/sendmail takes quiet some time to return even for a trivial message For eg. sendmail -f r...@netcore.co.in r...@netcore.co.in < /etc/hosts I need to identify the bottle neck. Do I need better CPU , or better harddisks. There seems to be plenty of RAM free though
