Hi,
I would like your opinion if our mailrelay is properly tuned:
I have a mailrelay (sendmail / mimedefang / spamassassin with fuzzyocr,
razor and dcc) running on a Sun V20Z with 6 GB Ram and 2 AMD 1.8Ghz cpu's
on Solaris 10.
it currently handles 95000 mails per day (most of it spam ofcourse). Load
is currently constantly around 6 - 7, average scan time of a mail is about
7 seconds. %io according to top is almost 0.
mimedefang spool is running on a ramdisk, and all the software is at the
most recent version
Does this seem like a normal load ? I had hoped that our upgrade from
solaris 9 to solaris 10 would have drastically improved the number of
emails the system could process (or lower the load for the same amout of
emails), but I don't notice a major improvement.
I'd appreciate your input on this matter.
regards,
tom.
Don't confuse the load average figure with 'overloaded' systems.
the load figure just means X processes are waiting for some resource
(CPU or disk or network or....).
Depending on your setup you may find it useful to use milter-ahead (or a
free equivalent) to drop email to unknown users before you send it off
to spamassassin etc for further processing. I drop over 2/3rds of my
traffic that way.
Given it's only 7 seconds to scan the email I'd says your system is more
than handling the traffic being processed.
