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?) 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)? I've been using qpsmtpd for a few months, (tried mostly forkserver version) but couldn't get those numbers (yet) I'll be giving a try to prefork and/or nonblock It would be nice to read about your setups in "who_uses" wiki My case: In the fork server, if the filters on the pre-connection stages are too quick, the number of process go to --limit-connections instantly, adding the "sleep 1" and giving timeouts to some of the clients. That's because I'm having a very quick father and a little slow children, if I set a high limmit-connections value (250), the load average goes to 20 or more. I tried to move pre-connection to connection so forked process do the filtering stuff, but it did'nt get any better. Saludos -- Leonardo Helman Pert Consultores Argentina
