<p class=MsoNormal>I was looking at those yesterday because I was running the
load average up to 10 or 12 in spurts. My box has a Sempron 2200 and a gig of
RAM, so it does swap when it gets busy. I can upgrade to a machine that's half
again faster with twice the memory for the same monthly fee, but I'd have to
run both during the transition and it would take a ton of time to move
everything over. (It's a webserver for a couple of dozen domains and my
secondary name server.)<br>
<br>
I told Sendmail to stop accepting connections at load average of 6, which kept
the load average from trying to get to 50. (Yes, I have seen the la go that
high, although not on this system. It ain't pretty!)<br>
<br>
I dropped the child count from five to three, which seemed to help - each child
just took bigger bites and the throughput didn't seem to be affected.<br>
<br>
One thing that looked appealing was setting up a caching nameserver, but all
the docs I ran into assumed that you weren't already running BIND on the box
and that you wanted to cache your local network, so I was too confused to get
that running. (I do have everything installed, just need to figure out the
config.)<br>
<br>
I did add pause-greet to the Sendmail config, it blocked at least a hundred
messages overnight. Not a big change, but the price is right.<br>
<br>
I'm thinking about setting up greylisting, it will cut down on the MS load and
should spread out the surges a little.<br>
<br>
I guess I should have expected things to slow down when I leapfrogged so many
versions on Tuesday. Now I've got to figure out how to get it back in control
or bite the bullet and get some more horsepower.<br>

<p><span lang=EN-GB>Hi All,</span><o:p></o:p></p>
<p><span lang=EN-GB> </span><o:p></o:p></p>
<p><span lang=EN-GB>Recently I am finding that the amount of incoming mail
through my MailScanner Server is really slowing down things. There
is a heavy load now since I took on a domain that seems to me well spammed.
Yesterdays processing processed 22,000 emails @88% Spam approx.</span><o:p></o:p></p>
<p>Server Spec POWEREDGE 1850 XEON 2.8GHZ/2MB 800FSB – WITH 2 GIG RAM and
RAID 1 Configuration on two Disks RPM 10K… Its Running Fedora Core
5, Send Mail 8.13.8-1.fc5 with MailScanner 4.69.7-1 with SA, Razor, DCC.,
MailWatch V1<o:p></o:p></p>
<p>Its working very well blocking spam, but only in the last couple of days its
got really slow. <o:p></o:p></p>
<p>Any ideas on how to reduce the load on this server>? By blocking mail at
the MTA before it hits MS? OR Tweaking my processes?<o:p></o:p></p>
<p>What do the Experts think on the Server Spec, for the amount of traffic?<o:p></o:p></p>
<p>I’d appreciate any help<o:p></o:p></p>
