Subject: [exim] Exim And SpamAssassin And Performans ...
Hi Everybody,

            We want to handle 50,000 mail/hour with using SpamAssassin. Dual
Xeon Machine / 4GB ram  and SATA disk with RAID 1 . I know disk system is
not good maybe scsi or raid 10 like config needed but I installed exim 4.50
with compiling WITH_CONTENT_SCAN=yes , and installes spamassassin 3.0.4 with
using yum on FC3 with making correct settings , it's start to work . Child
process is default 5 but I setted it to 20 because machine is dual ... after
that I tried to send mail with using WorldMerge which is mail sending client
and I setted 50 sim. Connection . I2m running 4 different WorldMerge for
reaching sim. 200 conncetion at this moment I 'm sending 9K mails .   After
that my top out is like below  


            Exactly I don't know but with this configuration I have to scan
more mail and more sim. Connection I think ? What do you think ? 


            Am I dreaming ? with scanning with this config 50,000 m/h ,
because some commercial hardware devices are scaning 30000-50000 mail/hour
with this config and also virus included ! 


            Using sa-exim or mailscanner can imporve performans or not ?
Because I think that using exim built-in connectivity between exim and
spamassassin must be better then others ( I guess ) 


            I'm installed spamassassin with default config , no razor or
pazor there , no extra things ....  Any body advise and knowledge about it ?
