Hi, I'm having some performance issues lately.
For those people managing big ISP's qpsmtpd's, how
is your general configuration?
What server version are you using?
qpsmtpd
qpsmtpd-forkserver
qpsmtpd-prefork
qpsmtpd-server
0.3x? or another svn branch? (or some private version of qp?)
We use qpsmtpd 0.32 with patches for qpsmtpd-prefork - our qpsmtpd
servers get 13million+ emails a day, which get scanned by
spamassassin, clamav and kaspersky.
I've read somewhere Ask is having 2000+ concurrent connections
in apache.org (or was it in perl.org?)
Is that true? 2000+ forked process in forkserver seems too much
are you using prefork? or qpsmtp-server (nonblocking)?
When you are talking about concurrent connections are you then
refering to established connections from netstat ?, or actual
connections doing qpsmtpd work ?.
We can handle the first using prefork with idle_connections set to 25,
maximum set to 120 and max pr ip to 10. The later will require a
monster machine (one qpsmtpd child pr case with 2000 connections would
kill even very big servers).
