Hi,
Since I updated to 10.3, I find spamd/spamc sluggish. My mail
fetching setup is:
fetchmail --> postfix --> procmail --> spamc/spamd
A mail is scanned, then it stops for some seconds (almost no cpu usage)
then it continues. It takes around 8 seconds per single email to check. I
think it is querying some of the network databases that is slow.
The other detail is that it only processes two mails at a time, I mean,
postfix spawns two children only:
root /usr/lib/postfix/master
postfix \_ qmgr -l -t unix -u
postfix \_ local -t unix
cer | \_ /usr/bin/procmail
cer | \_ /usr/bin/procmail
cer | \_ /usr/bin/spamc -s 350000
postfix \_ local -t unix
cer | \_ /usr/bin/procmail
cer | \_ /usr/bin/procmail
cer | \_ /usr/bin/spamc -s 350000
postfix \_ pickup -l -t unix -u
postfix \_ showq -t unix -u
I believe this is controlled in /etc/postfix/master.cf by this line:
local unix - n n - 4 local
or perhaps this one:
procmail unix - n n - 5 pipe
flags=R user=nobody argv=/usr/bin/procmail -t -m /etc/procmailrc ${sender}
${recipient}
but according to that, I should get 4 (or 5) children... so I must be
missing something. My idea is that if could get more emails to be
processed simultaneously (while one waits another is scanned) then
throughput would be faster.
