Re: Performance of mailserevr in FreeBSD 5.4
On Tue, 20 Sep 2005, Deepak Naidu spaketh thusly: -}Thanx Randy, -} -} It would be good, if I have some data of posted doc regarding this... or of -}your own experience. Thanx for your advise Ok. I'm posting this to advocacy as well in case any find it useful or at least interesting. Here's a summation of the testing I did and the results of those tests. As we were only looking for a few things this is far from a scientific analysis so FWIW. Test background/setup: I wanted to test various configs to see what gave the best throughput in a relay configuration for our real-time requirements, i.e. ave # of recipients, ave size of each email, etc. - OS's: FreeBSD 5.4 with and w/o softupdates, Fedora Core 3, Fedora Core 4. The FC installations used ext3 for the filesystems. I wanted to try with Reiser but ran out of time. - Sink systems simply threw everything to /dev/null. We had multiple sink systems to ensure they were never a chokepoint. - Source systems used fbsd's postal package as: postal -m 11 -p 4 -c 2 d3 usernames - where usernames contained 2 and 3 usernames. No significant difference was found using 2 or 3 usernames. - Test relay was a dual-proc 800 MHz system PC with 1 GB RAM and the entire system on 1 5400 RPM drive. (I know - nobody would ever run a mail server with /var/spool on the root drive but we were really just looking for difference percentages, not max throughput and had some old systems lying around... ;) - All installs were default installs. I thought about tweaking this or that, e.g. postfix has some notes on things to do for high-volume installations that we didn't do. I wanted out-of-the-box as much as possible. Tweaking can quickly turn into a slippery slope of just 1 more here and 1 more there. I figured we can tweak all we want for more specific needs as they arise. - The versions of sendmail and postfix were whatever was current stable in June, compiled locally with default build instructions. So, given all that, here's the #'s I came up with. Sendmail Linux:47,000 emails/hr FreeBSD: 66,000 emails/hr this is about a 40% increase in throughput. Postfix Linux: 86,000 emails/hr FreeBSD: 223,000 emails/hr this is about a 260% increase in throughput. The above data is for FC4 and FBSD 5.4 with softupdates enabled. My apologies but I can't find the notes for FC3 and FBSD w/o softupdates. FC4 was faster but not by much, and by about the same % for sendmail and postfix. Softupdates showed a similar pattern(as expected) - not as fast as with softupdates. IIRC the data for postfix/fbsd w/o softupdates was still around 190k emails/hr(this is from memory so take it with a grain of salt). I was amazed at the difference with postfix. Whatever Mr. Venema did inside postfix really works well on fbsd. Even though I can't find the #'s I remember my amazement that fbsd w/o softupdates still smoked FC4 when using postfix. Pls remember this is far from a scientific analysis. Your mileage will vary in many ways. I would recommend doing your own tests with your own criteria. -- Randy([EMAIL PROTECTED]) 715-726-2832 email bodhisattva * There is no fire like passion, there is no shark like hatred, there is no snare like folly, there is no torrent like greed. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: Performance of mailserevr in FreeBSD 5.4
Thnax to you all... We have done a black box testing and seems FreeBSD is rocking, except when SA is set to yes, Spamassasin(SA)... it just timesout.. It s my look out, might be RAM issue... Thanx for the feedback...

Re: Performance of mailserevr in FreeBSD 5.4
I have configured four servers using FreeBSD 5.3 with the following ports : - Postfix - Amavisd-new - SpamAssassin - Dcc - Courrier-IMAP - Clamav Not only is this working very well, but It's easy to update and very steady. One of the configuration I have is load balancing the trafic (using MX DNS) between 2 servers (1U 3Ghz Intel proc). Servers are processing mail (virus scanned - user verification using LDAP - spam checked) and delivering them inside a network wher people are collecting them. More than 10.000 mails are processed every day no problem. If you need more detail - let me know. Sincerly yours.

Thanx buddy, I am no way underestimating nay OS, but

hope u can understand.
