It depends how much concurrency you do. qpsmtpd-async was written for "ludicrous" concurrency (to paraphrase SpaceBalls). So there's a cut-off point at which qpsmtpd-prefork is faster (probably up to about 400 concurrent connections), after which qpsmtpd-async ends up being faster (well, more stable) because OS's really aren't very happy with 400 processes all trying to do accept() at the same time (the old "thundering herd" problem). >>> The subversion version is quite stable; indeed it's almost certainly >>> better than the last release. >> >> There's a message there ... :-) > > "quite stable" means different things to different people ;-) Could > you elaborate? svn HEAD is very stable. The message is that we actually need to cut a new release instead of just talking about it. Matt.
